lovato sm1r0100 sm1 rotary control motor circuit breaker 0.63 - 1 amp

Why Choose the SM1R0100?

Optimise motor protection with the Lovato SM1R0100 motor protection circuit breaker. This compact, 3‑pole Type E device combines thermal and magnetic protection, with a 0.63–1 A adjustable setting to suit fractional‑load motors. Delivering a high short‑circuit breaking capacity of 100 kA at 400 V and controlled via a robust rotary knob, it provides dependable isolation and protection in demanding industrial control panels.

Engineered for longevity and compliance, the SM1R0100 offers Ui 690 V, Uimp 6 kV, and a mechanical life of 100,000 cycles. It operates from −20 to +60 °C up to 3000 m altitude, with terminals tightened to 2.5–3 Nm. Conforming to IEC/EN 60947‑1/‑2/‑4‑1 and UL508 and CSA C22.2 No. 14, it integrates seamlessly into global panel designs.
