GE AK-50 installation instructions

INTRODUCTION

GE Conversion Kits are designed for upgrading

existing GE low-voltage power circuit breakers,

rather than replacing the entire breaker. The Con-

version Kits include ProTrip™ Trip Units, the latest

technological advance in GE trip systems.

ProTrip Conversion Kits are designed and tested to

conform to ANSI Standard C37.59, allowing the

retrofitter to properly install the kit and acceptance

test the breaker.

This publication covers installation of ProTrip Con-

version Kits on GE types AK-50, AKU-50, AKS-50,

AKT-50, AK-75, and AK-100 low-voltage power circuit

breakers. Each Conversion Kit contains all the

components needed to convert from an existing GE

type EC trip system.
