Motor Protection Circuit Breakers SM1P

lovato_logo

SM1P motor protection circuit breakers with
thermal and magnetic trip releases and high breaking
capacity.
Motor control and protection of up to 22kW (400V) is
possible by choosing the suitable adjustment range, from
0.1 to 40A.
The dimensions of SM1P… motor protection circuit breakers are compliant with the
DIN43880 standard, allowing them to be mounted in all
modular enclosures on the market.
A magnetic trip indicator integrated on the SM1R…
breakers avoids dangerous closing operations during short circuit
conditions, previously disconnected by the breaker.

Their high breaking capacity permits the elimination of
protection fuses on the majority of installations.
