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.
Motor protection circuit breakers such as the Lovato SM1RE3200 combine manual switching with dedicated protection against motor overloads and short circuits. The adjustable thermal release allows the protection level to be matched to the motor's rated current, while the magnetic release responds rapidly to high fault currents.
The SM1RE3200 is designed for demanding industrial motor circuits and provides an IEC ultimate short-circuit breaking capacity of 50 kA at 400 V AC. Its compact SM1R construction, rotary control and flexible mounting options make it suitable for use as part of motor starters, machinery control panels and industrial power distribution systems.
