Carlo Gavazzi Modular Motor Protection System

Sords Electric and Carlo Gavazzi New Motor Protection System

CARLO GAVAZZI is proud to launch the DMPU Series Motor Protection System. The DMPU is a modular electronic motor protection relay to control, monitor and protect the performance of 3-phase constant or dual speed, AC induction motors. The DMPU device measures electrical motor variables (voltage, current, harmonic distortion, power, energy and earth leakage current), monitoring overloads through the thermal model, controlling them and measuring other variables, such as motor and bearing temperature. Finally it includes a data logger function for storing trends of the electrical variables, alarms and fast data logging for storing start-up profiles.

Through the communication features, it is possible to transmit all monitored variables to a supervision control system for data collection and process control. Profibus and Modbus TCP/IP protocols are available to easily insert the DMPU Series into a majority of applications. The HMI operator interface is freely programmable and can show instantaneous values and alarm messages. Windows based DMPU-PS configuration and monitoring software, simplifies plant design through graphic block configuration and connection, where the blocks are all the variables that can be used, as inputs, outputs, ANSI function, electrical and temperature variables, logical functions, timers and counters.

The DMPU Series allows protection of the motor against damage due to thermal effect taking place during overload condition. The protection trips when motor temperature exceeds calculated TCU parameter as well as optional temperature measurements and electrical variables. The DMPU implements several ANSI functions to protect motor from operation that may damage it. For example ANSI 46 (motor inverse current), ANSI 51 LR and ANSI 48 (locked or stalled rotor) and ANSI 46 (earth leakage) are among few that are supported. All control functions such as start, stop, reverse, star-delta control and alarm indication are possible with push buttons, touch screen HMIs or communications.

Modular concept including these modules:

	DMPUT-MBT: Modbus TCP/IP communication
	DMPU-PRB: Profibus communication
	DMPU-05: Current and voltage measurements
	DMPU-R2: 2 temperature or digital input & 2 outputs
	DMPU-EL: Earth leakage module
	DMPU-HMI: Simple, two line HMI operator panel
	BTM-T4/T7: 4.3” and 7” touch screen interfaces

Other features include:

Meltric DS30 Industrial Plugs & Receptacles

DS 30 DeContactors by Meltric and Sords Electric

Meltric's DS30 Industrial Plugs and receptacles offer safety, convenience and money savings opportunity for the industrial and commercial workplace.  By meeting NEC codes and NFPA 70E requirements, there is no equal in the quick connect industrial plug market. The dead front construction of the female receptacle, keeping the hot contacts secured from being accidentally touched is unique in the industry.

SAFETY - Dead Front Construction and a RATED Disconnect Switch 
CONVENIENCE - Quick Change outs over hard wiring
MONEY - No Special Suits - Quick Change Outs - SAFE!

Qualified maintenance workers can quickly connect or disconnect welding machines, motors, and other equipment in complete safety. Once the plug is removed it provides visual verficiation of deenergization. The safety shutter on the receptacle prevents exposure to live parts and maintains an NFPA 70E defined hazard risk category = 0. The need for cumbersome PPE to meet NFPA 70E standards can be avoided.

Meltric Decontactors (Switch Rated Plugs and Receptacles) can be used in the follwoing applications:

HVAC :
Workers are exposed to live parts and risk arc flash injury when opening and disconnecting standard blade type disconnect switches. Instead, to prevent accidents and simplify code compliance install UL/CSA switch rated plugs and receptacles from Meltric. They are a combination plug, receptacle and disconnect switch in one device. Meltric's receptacles/connectors feature a built-in switching function that ensures the contacts are safely deenergized before the plug can be withdrawn. Once withdrawn, the plug provides visual verification of deenergization. Arc flash safety is ensured and HVAC service work becomes safer and easier.

PUMPS :
Meltric Decontactor plugs and receptacles are ideal for pump connections up to 60 hp or 200 amps. Using Decontactors to connect power to pumps instead of hard-wiring can reduce downtime related to pump servicing by 50% or more. A qualified technician can safely disconnect power to the pump simply by removing the Decontactor plug which can then be easily locked out to ensure safety. The technician can then service the pump in complete safety. When service work is complete the technician can reconnect power simply by plugging the Decontactor plug back into the receptacle.

TRAILER :
Meltric's DECONTACTOR™ Series “trailer plugs” and receptacles are a combination plug, receptacle and UL/CSA approved disconnect switch in the same device. Decontactors are commonly used to connect power to trailers from a portable generator or from a shore power source. Safety features prevent exposure to arc flash and live parts. Code compliance is greatly simplified because the trailer plug safety features ensure an electrically safe work condition.

WELDING :
Workers risk exposure to arc flash when disconnecting standard welder plugs and receptacles. To prevent accidents install UL/CSA switch rated welder plugs and receptacles from Meltric. They are a combination plug, receptacle and disconnect switch in one device. Meltric’s receptacles/connectors feature a built-in switching function that ensures the contacts are safely deenergized before the welding machine plug can be withdrawn. Arc flash safety is ensured. By having the male plug already wired to the welder, moving the welding apparatus around the plant becomes safe and easy!

GENERATOR :
Workers risk exposure to arc flash when disconnecting standard generator plugs and receptacles. To prevent accidents install MELTRIC UL/CSA switch rated generator plugs and receptacles from Meltric. They are a combination plug, receptacle and disconnect switch in one device. Meltric’s receptacles/connectors feature a built-in switching function that ensures the contacts are safely deenergized before the generator plug can be withdrawn. Arc flash safety is ensured. With multiple recepatacle available on a generator, quickly connecting and disconnecting the right plug into the right receptacle is safe and easy.  Color coded voltage gaskets and "keyed" insertion means the right plug and receptacle go together every time and never a mistake.

CORD DROP and HOIST :
MELTRIC Decontactor plugs and receptacles are designed and rated to make and break electrical loads in complete safety while providing users with significant protection in the event of overloads or short circuits. Special protective equipment and training are not required to make and break connections. MELTRIC DECONTACTOR™ Series switch rated plugs and receptacles are ideal for connecting power to hoist systems. They ensure safety and enable plug and play hoist change-outs. An electrically safe work condition is ensured even when disconnecting under load plus NFPA 70E compliance is greatly simplified. NO SUITS, NO MESS, NO DANGER.

SHORE POWER :
Meltric's shore power plugs and receptacles are ideal for marine ship to shore power connections. Meltric industrial plugs and receptacles offer superior durability and safety relative to pin and sleeve or twist type devices. The silver-nickel, butt style contacts perform particularly well in harsh saltwater environments and safety features ensure protection from arc flash.

MOTORS :
Using Meltric Decontactor plugs and receptacles to connect motors instead of hard-wiring can help to reduce equipment change-out downtime by as much as 50%. Optional integral auxiliary contacts can be used to communicate motor temperatures back to a control center so preventative maintenance can be performed before motor failure occurs.When replacement motors are pre-wired with Meltric Decontactor inlets or plugs, a mechanic can safely perform the electrical connections simply by unplugging the old motor and plugging in the new one. SAFE, QUICK, EASY. Meltric Makes It Easy!

Sections 430.102 – 430.109 of the National Electric Code require approved disconnecting means to be located in a readily accessible location within sight of the motor and driven equipment. With their UL & CSA ratings for “Motor Circuit Disconnect Switching” and “Branch Circuit Disconnect Switching”, Decontactor devices are an approved ‘line of sight’   disconnect switch for meeting this requirement.
