Why Choose the Lovato SM1X1422060 Undervoltage Trip Release?
The Lovato SM1X1422060 is an undervoltage trip release designed for compatible Lovato SM1 motor protection circuit breakers. Operating from a 220 V AC, 60 Hz supply, it provides automatic tripping when the control voltage falls below the specified operating threshold, helping prevent machinery from remaining energised or restarting unexpectedly following a significant loss of supply voltage.
As part of the Lovato Electric SM1X accessory range, the SM1X1422060 is designed for use with SM1P and SM1R motor protection circuit breakers. The release snaps onto the side of the compatible breaker and provides a dedicated undervoltage function without requiring a separate external tripping device.
The SM1X1422060 has a release voltage range of 35–70% of Us and an operating voltage range of 85–110% of Us. Its coil consumes approximately 12 VA during inrush and 3.5 VA while holding, while an IEC rated insulation voltage of 690 V and impulse withstand voltage of 4 kV support dependable operation in industrial motor control applications.

Reliable Undervoltage Protection for Motor Circuits
An undervoltage trip release causes a compatible circuit breaker to open when its supply voltage falls below a defined threshold. This functionality is particularly useful in motor control applications where equipment should be disconnected following a substantial voltage reduction or supply failure and should not remain mechanically latched in the operating position without the required control voltage.
The Lovato SM1X1422060 is engineered specifically for compatible SM1P and SM1R motor protection circuit breakers. With a 35–70% Us release range and an 85–110% Us operating range, it provides predictable undervoltage behaviour while integrating directly with the associated motor protection device.
Typical Applications
- Industrial motor control panels.
- SM1P and SM1R motor protection circuit breaker installations.
- Machinery requiring undervoltage release functionality.
- Pumps, fans and compressor control systems.
- Conveyors and material handling equipment.
- Industrial automation and machine control systems.
