Why Choose the Lovato P1MBUH2PD05 Miniature Circuit Breaker?
The Lovato P1MBUH2PD05 is a compact two-pole miniature circuit breaker (MCB) designed to provide thermal-magnetic overcurrent and short-circuit protection in industrial electrical distribution and control systems. Part of the Lovato P1 MBUH UL489 range, it combines a 5 A rated current with Curve D tripping characteristics for dependable branch circuit protection.
The P1MBUH2PD05 is rated for 480Y/277 V AC systems and provides a 10 kA short-circuit breaking capacity. Its two protected poles provide coordinated protection and disconnection, while UL489 compliance makes it suitable for branch circuit applications in appropriately designed industrial machinery, automation systems and electrical control panels.
A Curve D tripping characteristic makes this breaker particularly suitable for compatible circuits that experience relatively high transient or starting currents. With its compact two-module format, DIN rail mounting, IP20 protection and conductor capacity up to 35 mm², the P1MBUH2PD05 provides a practical solution for demanding industrial installations.

Reliable Curve D UL489 Branch Circuit Protection
The Lovato P1MBUH2PD05 uses thermal-magnetic protection to interrupt excessive current caused by overloads or short circuits. Its thermal element responds to sustained overload conditions, while the magnetic mechanism provides rapid operation during severe fault-current events, helping protect conductors and connected electrical equipment.
Its Curve D characteristic provides increased tolerance of transient inrush currents compared with more sensitive trip curves, making it suitable for compatible inductive and high-starting-current loads. Combined with its 5 A rating, 480Y/277 V AC system capability, two-pole construction and 10 kA breaking capacity, the P1MBUH2PD05 provides effective branch circuit protection for industrial applications.
Typical Applications
- Industrial electrical control panels.
- UL489 branch circuit protection.
- 480Y/277 V AC electrical systems.
- Industrial machinery and automation equipment.
- Compatible transformer, solenoid and power supply circuits with higher inrush currents.
- OEM electrical control and distribution assemblies.
