Why Choose the Lovato P5X14E048UL Undervoltage Trip Release?
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.

Automatic MCCB Release During Undervoltage Conditions
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.
Typical Applications
- UL-certified Lovato P5ME MCCB installations.
- Industrial machinery control systems.
- Low-voltage power-distribution panels.
- Industrial switchboards and control panels.
- Equipment requiring automatic release following control-voltage loss.
- Manufacturing and processing machinery.
- OEM machinery using 48 V AC/DC control circuits.
- Industrial automation and power-control systems.
