Why Choose the Lovato P5X14A440 Undervoltage Trip?
The Lovato P5X14A440 is an undervoltage trip accessory designed for compatible Lovato P5M moulded case circuit breakers. It provides automatic breaker tripping when the control supply voltage falls below the permitted operating level, helping protect machinery and electrical systems against unsafe operation following a significant loss or reduction of supply voltage.
Designed as part of the Lovato P5 MCCB accessory range, the P5X14A440 is installed within the circuit breaker and interfaces directly with its tripping mechanism. An undervoltage release also prevents the breaker from being maintained in the closed condition when adequate control voltage is unavailable, providing a useful fail-safe function in industrial distribution and machine-control systems.
The P5X14A440 is specifically rated for a 440–480 V AC control supply. It is intended for compatible P5M circuit breakers and provides a purpose-designed solution for applications where automatic disconnection following an undervoltage condition is required.
Key Advantages
- Purpose-designed undervoltage trip for compatible Lovato P5M MCCBs.

Reliable Undervoltage Tripping for P5M Circuit Breakers
An undervoltage release monitors the availability of its control supply and acts on the circuit breaker's operating mechanism when that voltage becomes insufficient. This allows the breaker to open automatically following a serious voltage reduction or complete supply loss and helps prevent equipment from remaining energised under unsuitable operating conditions.
The Lovato P5X14A440 integrates this functionality directly into compatible P5M moulded case circuit breakers. Its 440–480 V AC rating makes it suitable for industrial installations using corresponding control voltages, while the integrated design provides a neat solution for switchboard and machinery protection schemes.
Typical Applications
- Industrial P5M moulded case circuit breaker installations.
- Automatic disconnection following control-voltage loss.
- Industrial main and sub-distribution switchboards.
- Machinery power distribution and control systems.
- Motor control centres and industrial electrical panels.
- Manufacturing and process-control installations.
- OEM switchgear and panel-building applications.
