£126.94
The Lovato SM1RE1800 is a robust Type E manual motor starter and motor protection circuit breaker designed to provide reliable switching, overload protection and short-circuit protection for electric motors in industrial control systems. As part of the Lovato SM1R motor protection circuit breaker series, it combines thermal and magnetic protection in a compact three-pole device.
Designed for demanding machinery and automation applications, the SM1RE1800 features an adjustable thermal trip range of 13–18 A, phase-failure sensitivity and a rotary operating mechanism. Its high short-circuit breaking capability makes it suitable for installations where dependable protection and straightforward manual motor isolation are required.
The SM1RE1800 has a rated current of 18 A, a rated insulation voltage of 690 V and an ultimate short-circuit breaking capacity of up to 100 kA at 400 V AC. It is UL Type E approved as a manual self-protected combination motor controller and can be mounted on a standard 35 mm DIN rail or by screws.
Manual motor starters such as the Lovato SM1RE1800 combine switching and protective functions in a single compact device. The adjustable thermal release protects motors against sustained overload conditions, while the magnetic release provides rapid disconnection during high-current short circuits.
The SM1R series is designed for integration into industrial machinery, control panels and motor starter assemblies. Its Type E self-protected configuration, high breaking capacity and phase-failure sensitivity help provide dependable motor circuit protection while reducing the number of separate protective components required.
