lovato sm1p0040 sm1 push button motor circuit breaker 0.25 - 0.4 amp

Why Choose the SM1P0040?

Engineered for dependable motor protection, the Lovato SM1P0040 motor protection circuit breaker delivers outstanding short‑circuit performance with an IEC Icu of 100 kA at 400 V. With a 0.25…0.4 A thermal trip adjustment range and magnetic and thermal protection, this 3‑pole, push‑button controlled unit safeguards small motors while meeting IEC/EN 60947 standards.

With a rated insulation voltage Ui of 690 V and a 6 kV impulse withstand, the SM1P series device is built for reliability. It operates from -20 to +60 °C, up to 3000 m altitude, and endures 100,000 mechanical cycles. Terminals tighten to 2.5–3 Nm. Conforms to IEC/EN 60947 standards, UL508 and CSA C22.2 n° 14, and carries a Sustainability certification.
