Description
Lovato's SM1R series are modern circuit breakers with thermal and magnetic trip releases and high breaking capacity
- Motor control and protection of up to 22kW (400V) are possible by choosing the suitable adjustment range, 0.1 to 40A
- A magnetic trip indicator integrated on the SM1R... breakers avoids dangerous closing operations during short-circuit
conditions, previously disconnected by the breaker - SM1R... up to 32A breakers, with SM1X9000R or SM1X9050 accessory, are Type E-certified according to UL 60947-4-1; only for range from 6.5 to 32A the Type E version must be ordered with specific code SM1RE.... SM1R... motor protection circuit breakers combined with BG... and BF... contactors are Type F certified in compliance with UL 60947-4-1 standard
- SM1R motor protection circuit breakers are suitable for isolation in accordance with IEC/EN/BS 60947 standards and can be padlocked in OFF position without using accessories
- Their high breaking capacity consents to exclude protection fuses on the majority of the installations
