Eaton PKZM0-1.6-T Transformer Protection Circuit Breaker, 3-Pole, 1.0-1.6 A, Rotary Handle 088912

Transformer protection circuit breaker with thermal overload and magnetic short-circuit release, rated up to 1.6 A. The PKZM0-1.6-T safeguards transformers against overloads and short circuits with a precise adjustable trip range from 1.0 to 1.6 A and a magnetic release at approximately 20 times the rated current.

Advantages

Manual rotary handle operation allows clear ON/OFF switching and status indication. Screw terminals ensure secure wiring, while DIN rail mounting simplifies installation in control panels. The 3-pole design provides complete isolation and protection for three-phase transformer circuits.
