LOW POWER GROUND FAULT

INTERRUPTER



DESCRIPTION

The UTC GV4145A is a low power controller for AC outlet

ground fault interrupters. These devices detect hazardous

grounding conditions, such as equipment (connected to opposite

phases of the AC line) in contact with a pool of water and open

circuits the line before a harmful or lethal shock occurs.

Contained internally are a 26V zener shunt regulator, an

opamp, and an SCR driver. With the addition of two sense

transformers, a bridge rectifier, an SCR, a relay, and a few

additional components, the UTC GV4145A will detect and protect

against both hot wire to ground and neutral wire to ground faults.

Ease of application and long-term reliability.


