lovato sm1p1400 sm1 push button motor circuit breaker 9 - 14 amp

Why Choose the SM1P1400?

Engineered for dependable motor circuit protection, the Lovato SM1P1400 motor protection circuit breaker combines thermal and magnetic trip functions in a compact, 3‑pole design. With SKU SM1P1400, it delivers an IEC short‑circuit breaking capacity Icu of 25 kA at 400 V and an adjustable thermal range of 9...14 A, helping you set precise protection aligned to motor full‑load current and installation fault levels.

Conforming to IEC/EN 60947-1, 60947-2 and 60947-4-1, plus UL508 and CSA C22.2 n° 14, this SM1P device offers Ui 690 V and Uimp 6 kV insulation performance. Push‑button control simplifies setup and testing, while durable mechanics provide 100000 cycles. Rated for -20 to +60 °C operation, up to 3000 m altitude, and 2.5–3 Nm terminal torque, it integrates reliably into industrial control panels.
