Type K characteristics have been specifically designed for the protection of motor control circuits and items used within them. It has a very sensitive thermal curve, combined with a magnetic setting of 8 times the normal input current (In), which is high enough to avoid in-rush nuisance tripping, but provides good protection against over current conditions.

DIN rail mounting

The Classic & System pro M product cannot be intermixed and do not share common accessories. System pro M products can only be fitted to new style Protecta distribution boards.

Reduce the risk of power spikes damaging your industrial equipment with this MCB from ABB. The type-K breaker is an ideal choice for machinery that experiences inrush currents or high inductive loads, thanks to its ability to trip currents between 8 and 12 times its 16A rating. For comprehensive safety, the unit includes a delayed thermal tripping mechanism for overload protection, as well as an electromagnetic tripping feature to handle short circuits. Its contact position indicator allows for quick and convenient visual inspection of status.
