Why Choose the SM1R0650?
Designed for dependable motor protection, the Lovato SM1R0650 motor protection circuit breaker (Type E) delivers high fault withstand with IEC Icu 100kA at 400V. Its adjustable 4…6.5 A thermal trip and combined magnetic and thermal protection guard motors against overloads and short circuits. A positive rotary knob offers clear local control, while the 3‑pole SM1R platform supports coordinated motor starting in control panels.
Built for tough environments, this breaker offers Ui 690 V and 6 kV impulse withstand, with a mechanical life of 100000 cycles. It operates from -20 to +60 °C up to 3000 m altitude, with terminal tightening torque 2.5 to 3 Nm and 390 g weight. Conforms to IEC/EN 60947-1/-2/-4-1, UL508 and CSA C22.2 n° 14, and is certified UL Type E.
