lovato sm1p1800 sm1 push button motor circuit breaker 13 - 18 amp

Why Choose the SM1P1800?

Engineered by Lovato, the SM1P1800 motor protection circuit breaker (SKU SM1P1800) safeguards three‑phase motors with adjustable thermal trip from 13 to 18 A and combined magnetic and thermal protection. With 25 kA Icu at 400 V and push‑button control, this 3‑pole device delivers dependable fault interruption and straightforward operation across a wide range of industrial motor circuits.

Designed for resilience, the SM1P series offers 690 V rated insulation and 6 kV impulse withstand, with a mechanical life of 100,000 cycles. It operates from −20 to +60 °C and up to 3000 m altitude. Conforming to IEC/EN 60947-1, -2 and -4-1, plus UL508 and CSA C22.2 No. 14, it integrates reliably within compliant control panels.
