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, see the 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
• Additional coating protects circuit boards against harsh environment: Provides flexibility for different applications
• SE-107: UV-trip mode only: Eliminates chance of unauthorized change to trip circuit
