Littelfuse Startco SE-145 Ground-Fault Ground-Check Monitor

SE-145 Ground-Fault Ground-Check Monitor

Functions:

Monitors up to three portable power cables
Detects ground faults in each cable or connected equipment
Detects open ground-check loop, and shorted ground-check loop in each cable

Features:

Zener-characteristic termination assembly provides reliable ground-check-loop verification
Loop-resistance calibration not required
LED indication of Ground-Check Trip, Valid, Open, and Short for each cable
LED indication of Ground-Fault Trip and Sensor Health for each cable
LED indication of Power and Diagnostic Error
Exceeds requirements of CSA Standard M421-00 Use of Electricity in Mines with fail-safe ground-fault and ground-check circuits
Universal power supply accepts a wide range of ac and dc voltages
Optional 24/48 Vdc power supply
DFT (harmonic) filter prevents false ground-fault operation
Low open-circuit ground-check voltage is not a hazard to personnel
Wide range of ground-fault current and time set points
Conformally coated circuit boards
Uses the same termination assembly as the SE-135
Optional IEEE 802.3 (Ethernet) with Modbus TCP protocol
Free SE-MON145 PC-interface software
Five year warranty

Manual:

SE-145 Manual (Preliminary)

Typical Applications:

Mining, shore-to-ship power, pumps, and cranes
Used on systems up to 25 kV
For applications where protection is required only for a single cable, see the SE-134C

System Components:

The SE-145 requires an SE-TA12A-series termination device for each cable. An SE-CS10-series current sensor for each cable is required for ground-fault protection.
