DM-1000 Electronic Trip Unit (Standard Unit)
Call for Price
Replace your existing STR Trip Unit with confidence using the fully programmable, retrofittable, DM-1000 Electronic Trip Unit.
The DM-1000 ETU replaces the Masterpact M OEM?s inherently faulty STR type trip units which, unfortunately, often suffer from non-repairable, spurious tripping problems. The DM-1000 is form-fit manufactured to make retro-fitting the trip unit device as easy and as fast as possible and utilises the existing current sensor connections of the Masterpact Air Circuit Breaker (ACB).
