Why Choose the Lovato P5X14E024 Undervoltage Trip Release?
The Lovato P5X14E024 is a 24 V AC/DC undervoltage trip release designed for compatible Lovato P5ME IEC moulded case circuit breakers. As part of the Lovato P5 MCCB accessory range, it provides automatic circuit breaker tripping when the monitored control supply falls below the specified voltage threshold.
The P5X14E024 operates from a rated supply of 24 V AC or 24 V DC. Its release threshold is 35–70% of Us, while the operating voltage range is 85–110% of Us. This enables the accessory to prevent the associated circuit breaker from remaining closed when the control voltage is insufficient for safe or intended system operation.
Designed for installation beneath the front cover of compatible P5ME circuit breakers, the P5X14E024 uses snap mounting and screw terminals for straightforward integration. An average opening time of 50 ms, low 0.64 VA holding consumption and compact internal construction make it suitable for industrial machinery, switchboards and power distribution systems requiring undervoltage protection.

Automatic Undervoltage Protection for P5ME Circuit Breakers
An undervoltage trip release is used to automatically open a circuit breaker when its control supply falls below an acceptable level. With the Lovato P5X14E024, the breaker is released when the supply falls within the specified 35–70% Us trip range, helping prevent equipment from remaining energised during significant voltage loss or abnormal control supply conditions.
The undervoltage release also requires adequate control voltage before the associated breaker can remain closed. This characteristic is particularly useful in machinery and industrial control systems where automatic restart following a loss of supply may be undesirable. The P5X14E024 combines this functionality with a 24 V AC/DC control supply, compact internal mounting and straightforward screw-terminal wiring.
Typical Applications
- Industrial machinery undervoltage protection.
- Low-voltage electrical distribution boards.
- Industrial switchboards and control panels.
- Automatic circuit breaker release following control voltage loss.
- Machinery circuits requiring prevention of unintended restart.
- Power distribution and industrial automation systems using compatible P5ME MCCBs.
