£39.87
The Lovato SM1X14400 is a high performance undervoltage trip release designed specifically for use with Lovato SM1P and SM1R motor protection circuit breakers. It automatically trips the breaker whenever the control supply voltage falls below the specified operating threshold, helping protect personnel, machinery and electrical systems from unsafe operating conditions.
Operating from a 400 V AC 50 Hz or 440 V AC 60 Hz control supply, the SM1X14400 is ideal for industrial motor control applications where automatic restarting following a power failure must be prevented. It improves machine safety while ensuring reliable protection for industrial equipment.
Designed as a compact accessory for the Lovato SM1 series, the SM1X14400 installs directly onto compatible motor protection circuit breakers, providing dependable undervoltage protection for OEM machinery, control panels and industrial automation systems.
The Lovato SM1X14400 disconnects the motor protection circuit breaker whenever the control voltage falls below the permitted operating level. This prevents machinery from automatically restarting when power returns, improving operator safety and reducing the risk of equipment damage.
Designed for demanding industrial environments, the unit combines robust electrical performance with straightforward installation, making it an ideal accessory for OEM machinery, production equipment and industrial automation systems.
