SE-502 SERIES

Ground-Fault Ground-Continuity Detector

Description

The SE-502 Ground-Fault Ground-Continuity Detector provides

Class-A GFCI trip level and trip times for personnel protection.

As little as 5 mA of ground-fault current can be detected, and the

internal neutral-grounding resistor limits the maximum ground-fault

current to 100 mA. The SE-502 can be used on both energized and

de-energized systems, and will continuously monitor neutral

continuity, detect a load-side grounded neutral, and is capable of

ground proving. These features make the SE-502 ideal for use with

120/208 V portable generators and in heat-trace applications.
