SM1R

Lovato SM1R 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. The dimensions of SM1R 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. Up to 32A breakers, with SM1X90 00R 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. Lovato motor protection circuit breakers are suitable for isolation in accordance with IEC/EN 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.
