FAQ

What is the adjustable current range for the PKZM0-10?

The thermal overload protection is adjustable via the yellow dial on the front, with a range from 6.3 Amperes to 10 Amperes.

Can this circuit breaker be used for single-phase motors?

Yes, it can protect single-phase motors. For correct thermal protection, it is recommended to wire all three poles of the breaker in series with the motor load.

What is the difference between the thermal and magnetic trip functions on this device?

The thermal protection is a bimetallic strip that responds to sustained overcurrents (overloads) over time. The magnetic protection is an electromagnet that responds instantly to very high currents typical of a short circuit, ensuring rapid disconnection to prevent damage.
