Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-F...
Description
Single and multipole 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.
Industry standard dimensions and panel mounting. Options include
auxiliary changeover contacts. Low temperature sensitivity at rated
load.
Approved to CBE standard EN 60934 (IEC 60934).
Typical application
