lovato sm1p0650 sm1 push button motor circuit breaker 4 - 6.5 amp

Why Choose the SM1P0650?

Lovato’s SM1P0650 motor protection circuit breaker safeguards three‑phase motor circuits. It offers IEC breaking capacity Icu of 100 kA at 400 V, a thermal trip adjustment range of 4…6.5 A and a rated current of 6.5 A. Combining magnetic and thermal protection with push‑button control, this 3‑pole SM1P series device is specified to protect against overloads and short circuits in industrial installations.

Rated insulation voltage Ui is 690 V with impulse withstand Uimp of 6 kV, and mechanical life is 100000 cycles. Operating limits span −20 to +60 °C, with storage from −50 to +80 °C and installation up to 3000 m altitude. Terminal tightening torque is 2.5 to 3 Nm. Conforms to IEC/EN 60947‑1/‑2/‑4‑1, UL508 and CSA C22.2 n° 14, and carries a Sustainability certification.
