ALLIS-CHALMERS / SIEMENS

AC-PRO trip unit retrofit conversion kits are available for all vintages of Allis-Chalmers and SIEMENS circuit breakers. G style circuit breakers, as well as the early style LA-15, LA-25, LA-50, and LA-75 breakers were all manufactured with electro-mechanical series overload trip devices.

Newer style Allis-Chalmers LA and LAF breakers and the SIEMENS RL style breakers were all manufactured with electronic trip units. AC-PRO kits are in stock to replace all of these electronic trip units, including: LimiTrip, Dual-Static, Model-1A, StaticTrip I, Static Trip II, and StaticTrip III.
