Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-T...

Description

Single, two and three pole magnetic and hydraulic-magnetic circuit

breakers with trip-free mechanism and toggle actuation. A choice of

fast magnetic only or hydraulically delayed switching characteristics

(S-type MO or HM CBE to EN 60934) ensures suitability for a wide

range of applications. Featuring a combi-foot design for symmetric rail

mounting. Low temperature sensitivity at rated load.

Approved to CBE standard EN 60934 (IEC 60934).

Typical applications

Power supplies, control equipment, communication systems, EDP

systems.
