The Lovato P5X14E048UL is a 48 V AC/DC undervoltage trip release specifically designed for UL-certified Lovato P5ME moulded case circuit breakers. It provides automatic breaker release when the control supply falls below the specified voltage threshold, supporting controlled disconnection during undervoltage or loss-of-supply conditions.
Rated for both 48 V AC and 48 V DC, the P5X14E048UL has a release threshold of 35–70% of Us and an operating voltage range of 85–110% of Us. Its average opening time is approximately 50 ms, providing rapid operation when an undervoltage condition occurs.
The P5X14E048UL features snap mounting and screw-terminal connections for integration with compatible P5ME breakers. With cULus certification, a holding consumption of only 1.09 VA and support for 0.5–1.5 mm² flexible conductors, it provides a compact solution for UL-oriented industrial power and machinery applications.
An undervoltage release is used when a circuit breaker must respond automatically to an unacceptable reduction or loss of control voltage. The Lovato P5X14E048UL operates with a 48 V AC/DC control supply and has a specified release range of 35–70% of Us, causing the associated compatible breaker to open when the release conditions are reached.
The release is specified to operate normally at 85–110% of Us and has an average opening time of approximately 50 ms. This makes it suitable for machinery and industrial power-distribution systems where loss of control voltage needs to initiate rapid disconnection through a compatible UL-certified P5ME MCCB.

The P5X14E048UL is a 48 V AC/DC undervoltage trip release designed for compatible UL-certified Lovato P5ME moulded case circuit breakers.
The P5X14E048UL is rated for both 48 V AC and 48 V DC. Its rated frequency for AC operation is 45–65 Hz.
Lovato specifies a release voltage range of 35–70% of the rated supply voltage Us.
The specified operating voltage range is 85–110% of Us.
The P5X14E048UL has an average opening time of approximately 50 ms.
The P5X14E048UL is specifically intended for UL-certified P5ME MCCBs, whereas the P5X14E048 is the corresponding IEC-oriented version. Both are rated for 48 V AC/DC operation, but the correct accessory should be selected for the applicable breaker configuration.
The P5X14E048UL uses screw terminals operated with a PZ2 tool and accepts flexible conductors from 0.5 to 1.5 mm², equivalent to 20–16 AWG.
Yes. The P5X14E048UL is specified for UL-compliant MCCBs and carries cULus certification.
Lovato P5 moulded case circuit breaker accessories provide panel builders, electrical engineers, machine builders and industrial automation professionals with integrated trip, control and signalling functions for dependable low-voltage power-distribution systems.
