Eaton PKZM0-0.25-SP Motor Protection Circuit Breaker, 0.16-0.25 A, 3-pole, 690 V AC 199178

In industrial control panels and machine building, the Eaton PKZM0-0.25-SP motor protection circuit breaker reliably safeguards small three-phase motors against overload and short-circuit. With an adjustable overload release from 0.16 A to 0.25 A and a fixed magnetic trip at 3.25 A, it is precisely matched to the rated current of the connected motor. The 3-pole design and screw terminals allow straightforward DIN rail mounting in distribution boards or control cabinets.
