The motor switch PKZM0-0.25 is suitable for starters or short-circuit switches. It operates at currents from 0.16A to 32A and features a short-circuit mechanism, but no overload mechanism. It is used for the protection of resistance loads, where overloads are not expected.

Additionally, these switches are used in motor starter combinations, with or without restart blocking, if an overload relay or thermal protection mechanism is used.
