Mercury Displacement Relays are all designed and built to meet the most exacting demands of industry. They have won their high place in the electrical field by doing the tough and tricky jobs that ordinary equipment could at best do in an uncertain manner. They have proved their ability to stand up under the most adverse conditions of temperature, dust and moisture, in all types of applications.

The Mercury Displacement Industries (MDI) 30-AMP model is designed to save space and simplify mounting methods. The standard mounting bracket on the three pole model allows the unit to be mounted in standard 3” snap track channel. If you do not use snap track mounting, the standard three pole bracket has key hole slots for easy mounting in any panel arrangement. The 30-AMP series is a more compact line with a well proven switch which is the heart of mercury relays. It is the same switch design that is in our 35 and 60-AMP encapsulated MDR’s, which have withstood the test of time and millions of cycles in many different applications.

Carlo Gavazzi Single Compressor Soft Starters

 Carlo Gavazzi Single Compressor Soft Starters from Sords Elecric

CARLO GAVAZZI has launched the RSBS Series, a compact, single-phase soft-starter. The RSBS is designed for single-phase compressors and is an ideal solution in single phase voltage networks that are prone to voltage fluctuations. The high inrush current caused by starting compressors in these conditions can cause light to flicker, fuses to trip, generators to stall, and other disturbances.

The Carlo Gavazzi RSBS uses a current limiting algorithm to reduce compressor start current by more than 50% when compared to Direct Online (DOL) starters. Its control algorithm automatically detects when the compressor reaches full speed to make sure that the internal bypass relay switches ON when the current is at an optimum level. The RSBS can limit inrush currents up to 45 Amps under balanced conditions with a maximum ramp-up time of 600 ms. Its special HP function ensures the compressor receives enough starting torque by allowing a maximum current of 80 Amps even when the pressures are not balanced.

Features of the Carlo Gavazzi RSBS Single-Phase Soft Starter include:

• Single-phase 195.5 to 264.5 VAC, 50/60 Hz operating voltage range
• Current-limiting algorithm reduces inrush current by more than 50%
• Rated operational current: 37 Arms
• 4.4 kW / 5 HP rating at 40°C
• No user adjustments required
• Integrated diagnostics detect voltage dips, network interruptions and welded relay contacts
• Ideal for scroll compressors and piston compressors
• Anti-short cycling function with built-in delay between starts
• Auxiliary relay output with alarm status LED indication
• Choose from several different start capacitor sizes including an option for an external capacitor
• Agency approvals: cULus Listing and CE certification

The Carlo Gavazzi RSBS Series are the best choice for increasing reliability, reducing network interruptions, and improving compressor operation.
