lovato sm1p2500 sm1 push button motor circuit breaker 20 - 25 amp

Why Choose the SM1P2500?

Protect three‑phase motors with the Lovato SM1P2500 Motor Protection Circuit Breaker. It offers a 20…25 A thermal trip adjustment to match motor FLC, with IEC breaking capacity Icu 15 kA at 400 V for dependable fault interruption. Combining magnetic and thermal protection with push button control, the SM1P2500 suits motor feeders, starters and control panels, and conforms to IEC/EN 60947‑1/‑2/‑4‑1, UL508 and CSA C22.2 n° 14.

Engineered for reliability, the SM1P device provides Ui 690 V and 6 kV impulse withstand, with a mechanical life of 100000 cycles. It operates from −20 to +60 °C and stores between −50 and +80 °C, suitable up to 3000 m altitude. Connections are secured with 2.5 to 3 Nm terminal tightening torque, supporting consistent performance in industrial panels and OEM builds.
