Why Choose the Lovato P1MBUH1PD13 Miniature Circuit Breaker?
The Lovato P1MBUH1PD13 is a compact single-pole miniature circuit breaker (MCB) designed to provide thermal-magnetic overcurrent and short-circuit protection in industrial control and electrical distribution systems. As part of the Lovato P1 MBUH miniature circuit breaker range, it combines a 13 A rated current with Curve D tripping characteristics and UL489 compliance for branch circuit protection.
The P1MBUH1PD13 features a Curve D tripping characteristic, making it particularly suitable for circuits where relatively high transient or starting currents can occur. This characteristic makes it a practical choice for compatible transformers, power supplies, solenoids and other industrial loads where a conventional breaker with a more sensitive instantaneous trip characteristic could be unsuitable.
With a rated current of 13 A, a rated voltage of 277 V AC and a short-circuit breaking capacity of 10 kA, the P1MBUH1PD13 provides robust protection in demanding electrical installations. Its single-pole, single-module construction enables space-efficient installation on a standard DIN rail within machinery, automation and industrial control panels.

Reliable UL489 Branch Circuit Protection
Miniature circuit breakers such as the Lovato P1MBUH1PD13 automatically interrupt a circuit when excessive current results from an overload or short circuit. The thermal-magnetic operating principle provides overload protection together with rapid magnetic operation during severe fault-current conditions, helping protect conductors and connected electrical equipment.
The P1MBUH1PD13 combines UL489 branch circuit protection with a Curve D characteristic, making it particularly useful for compatible loads with elevated starting or transient currents. Its 13 A rating, 277 V AC rated voltage and 10 kA short-circuit breaking capacity make it a practical protection device for industrial machinery, automation equipment and electrical control systems.
Typical Applications
- Industrial electrical control panels.
- UL489 branch circuit protection.
- Industrial machinery and automation equipment.
- Transformer, solenoid and power supply circuits.
- Loads with relatively high transient inrush currents.
