TECHNICAL DATA

Low Power Ground Fault Interrupter

KK4145A

The KK4145AN 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 op amp, and an

SCR driver. With the addition of two sense transformers, a bridge rectifier,

an SCR, a relay, and a few additional components, the KK4145AN will

detect and protect against both hot wire to ground and neutral wire to

ground faults. The simple layout and conventional design ensure ease of

application and long-term reliability.
