Why Choose the SM1R2300?
Lovato’s SM1R2300 motor protection circuit breaker delivers dependable motor safeguarding in a compact, rotary‑operated form. With the adjustable 17–23 A thermal trip range and magnetic and thermal protection, it precisely protects motors while simplifying setup via the front rotary knob. A 3‑pole design and a high IEC breaking capacity of 50 kA Icu at 400 V AC make SKU SM1R2300 a robust choice for three‑phase applications.
Engineered for demanding environments, the SM1R2300 offers Ui 690 V and Uimp 6 kV, operates from −20 to +60 °C up to 3000 m, and achieves 100,000 mechanical cycles. Built to IEC/EN 60947-1, -2 and -4-1, plus UL508 and CSA C22.2 n° 14, it ensures broad conformity. Terminal screws tighten to 2.5–3 Nm, and the 390 g SM1R device streamlines motor protection in control panels.
