Description

Data sheet

Single- or multipole circuit breaker with magnetic or hydraulic-magnetic trip curve, threadneck or terminal block mounting and different trip curves. ON/OFF switching through push/pull actuation. The precise switching mechanism ensures reliable disconnection through an independent trip-free mechanism even at the slightest overcurrents. Low temperature sensitivity at rated load.

Meets the requirements of the EN 60934 (IEC 60934) circuit breaker standard for equipment protection: S-type, HM or MO.
