Why Choose the Lovato SM1RE3200 Manual Motor Starter?
The Lovato SM1RE3200 is a compact motor protection circuit breaker and manual motor starter designed to provide reliable switching, overload protection and short-circuit protection for three-phase motors. Part of the Lovato Electric SM1R series, it features an adjustable thermal trip range of 24–32 A and is certified as a UL Type E self-protected combination motor controller.
The SM1RE3200 combines thermal and magnetic protection within a single three-pole device. Thermal protection safeguards the connected motor against sustained overload conditions, while magnetic protection provides rapid response to short-circuit currents. The breaker is also phase-failure sensitive, helping provide comprehensive protection for demanding industrial motor applications.
With a rated current of 32 A, an IEC rated insulation voltage of 690 V and an ultimate short-circuit breaking capacity of 50 kA at 400 V AC, the SM1RE3200 provides robust protection in industrial installations. Its rotary operating knob and compatibility with 35 mm DIN rail or screw mounting make installation and manual motor control straightforward.
