Description
Typical applications
Approvals
Single and double pole magnetic and hydraulic-magnetic circuit breaker
with trip-free mechanism and toggle or rocker actuation. A choice of
fast magnetic only or hydraulically delayed switching characteristics (S
type MO or HM CBE to EN 60934/IEC 934) ensures suitability for a wide
range of applications. Low temperature sensitivity at rated load. Industry
standard dimensions and threadneck or snap in panel mounting.
Complies with CBE standard EN 60934 (IEC 934).
