High Performance Thermal-Magnetic Circuit Breakers 446/447/449
Description
Single pole thermal-magnetic circuit breakers with tease-free, trip-free,
press-to-reset snap action mechanism and special dual button manual
release which avoids the danger of unintended disconnection (M-type
TM CBE to EN 60934). Surface mounted, compact design available
with fast acting, standard and delayed switching characteristics.
Options include auxiliary contact and remote electrical disconnection.
Typical applications
Heavy duty vehicles, battery systems, process control.
