SM2R6300 Lovato rotary motor protection circuit beaker 45-63 amp

Why Choose the SM2R6300?

Engineered for demanding motor control, the Lovato SM2R6300 motor protection circuit breaker delivers dependable thermal‑magnetic protection across 45–63 A, with a rated current In of 63 A. With a high short‑circuit breaking capacity of 50 kA Icu at 400 V and a 3‑pole design, SM2R6300 safeguards three‑phase motor circuits. It aligns with IEC/EN 60947 standards and suits panels seeking robust fault interruption and accurate overload protection in a compact, installer‑friendly format.

Practical features include a rotary knob for straightforward setting and UL Type E certification for compliant motor branch circuits. Built to endure, it offers 1,000 V rated insulation (Ui), 6 kV impulse withstand (Uimp) and a mechanical life of 50,000 cycles. Reliable performance is maintained from −20 to +70 °C and up to 3,000 m altitude, all in a durable 1,000 g, SM2R‑series form factor.
