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.

Heavy duty vehicles, battery systems, process control.
