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.
