Why Choose the Lovato P5X14E048 Undervoltage Trip Release?
The Lovato P5X14E048 is a 48 V AC/DC undervoltage trip release designed for compatible Lovato P5ME moulded case circuit breakers. It provides automatic breaker tripping when the control supply falls below the specified release threshold, helping prevent connected equipment from remaining energised or restarting unexpectedly following an unacceptable loss of control voltage.
Designed for IEC-compliant P5ME MCCBs, the P5X14E048 has a rated supply voltage of 48 V AC/DC. The release operates when its supply falls within 35–70% of Us, while the specified operating voltage range is 85–110% of Us. Its average opening time is approximately 50 ms.
The P5X14E048 uses snap mounting beneath the circuit-breaker front cover and screw terminals for straightforward integration. It accepts flexible conductors from 0.5–1.5 mm² and uses a PZ2 terminal tool, making it a purpose-designed accessory for industrial distribution boards, machinery and electrical control systems incorporating compatible P5ME breakers.

Automatic Breaker Release During Undervoltage Conditions
An undervoltage trip release is used where a circuit breaker must automatically open if its monitored control supply drops below an acceptable level. With the Lovato P5X14E048 energised at its normal control voltage, the compatible P5ME breaker can remain closed; if the supply falls into the specified 35–70% Us release range, the release initiates breaker opening.
This operating principle is useful in machinery and industrial distribution systems where loss of control voltage should place equipment into a defined disconnected state. The P5X14E048's 48 V AC/DC rating, compact internal installation and approximately 50 ms average opening time provide a practical undervoltage-release solution for compatible P5ME circuit breakers.
Typical Applications
- Undervoltage protection for compatible P5ME MCCBs.
- Industrial machinery electrical systems.
- Low-voltage distribution switchboards.
- Machine control and automation panels.
- Manufacturing and processing equipment.
- Electrical systems requiring automatic disconnection after control-voltage loss.
- OEM machinery using 48 V AC/DC control circuits.
- Industrial power-distribution systems.
