SE-135 Ground-Fault Ground-Check Monitor
The SE-134C is recommended for most applications. The SE-135 should be used as a replacement for the SE-125, to maintain compatibility with existing termination devices. For additional information, please read the Littelfuse Startco Ground-Fault Ground-Check Comparison and the SE-125 to SE-135 upgrade documents posted in the Technical Information section.
Functions:
- Monitors portable power cable and detects ground faults in the cable or connected equipment, open ground-check loop, and shorted ground-check loop
- Can be used as a remote starter control
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
- LED indication of Ground-Fault Trip and Sensor Health
- 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
- 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
- Surface- and panel-mount hardware included
- Conformally coated circuit boards
- Five year warranty
- Uses the same termination assembly as the SE-125
Typical Applications:
- Mining, shore-to-ship power, pumps and cranes
- Used on systems up to 25 kV
System Components:
The SE-135 requires an SE-TA12A-series termination device.
An SE-CS10-series current sensor is required for ground-fault protection.
