The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-105/SE-107 is an excellent choice for trailing cables 5 kV and under in underground mining applications. For higher voltages or long-cable applications, use the Littelfuse SE-134C / SE-135. 

Features & Benefits

Adjustable pickup (0.5, 2.0, 4.0 A) Unit can be used on a wide variety of trailing cable applications 

Adjustable time delay(0.1 - 2.0 s)  Adjustable trip delay for quick protection and system coordination 

Harmonic filter Prevents false operation 

Zener-characteristic termination assembly Provides reliable ground-check loop verification 

Fail-safe ground-check circuit  Ensures ground-check circuit remains safe even in the event of equipment failure 

Conformal coating  Additional coating protects circuit boards against harsh environment 

SE-105: Selectable UV- or shunt-trip mode  Provides flexibility for different applications 

SE-107: UV-trip mode only  Eliminates chance of unauthorized change to trip circuit

SE-TA6-SM

Robust and compact stud-mount 50-W ground-check termination assembly with wire lead; replaces 1N4553B.

 

SE-TA6A Series

50-W ground-check termination assembly with convenient mounting holes and screw terminals. 

RK-102, RK-105, RK-105I

Remote Indication and Reset Assembly Remote indication and reset for the SE-105 and SE-107.  

 

RK-13

Separate ground-fault and ground-check indication contacts for the SE-105 or SE-107; separate ground-fault and resistor-fault indication contacts for the SE-325.

 

PPI-600V

The PPI-600V is a ground-wire device that allows a trailing-cable ground to be monitored independently of the parallel ground path created when trailing-cable-fed equipment is in contact with the earth. It also allows a trailing-cable ground to be monitored in the presence of stray dc and it prevents inter-machine arcing caused by the voltages induced in the cables.
