Why Choose the Lovato P1MBUH2PD06 Miniature Circuit Breaker?
The Lovato P1MBUH2PD06 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 MB range, it combines a 6 A rated current with Curve D tripping characteristics and IEC / UL489 compliance for dependable circuit protection.
The P1MBUH2PD06 is rated at 480Y/277 V AC under UL and provides a 10 kA short-circuit rating under both IEC and UL specifications. Its two-pole configuration occupies two DIN modules, providing coordinated protection in a compact format suitable for machinery, automation systems, OEM equipment and industrial control panels.
A Curve D tripping characteristic provides increased tolerance of high transient inrush currents, making this breaker suitable for compatible inductive and high-starting-current loads. With 125 V DC operational capability, a wide -40 to +70 °C operating temperature range and standard 35 mm DIN rail mounting, the P1MBUH2PD06 provides flexible protection for demanding industrial installations.

Reliable Curve D UL489 Circuit Protection
The Lovato P1MBUH2PD06 uses a thermal-magnetic operating mechanism to protect electrical circuits against sustained overloads and short circuits. The thermal element responds to prolonged overcurrent conditions, while the magnetic element provides rapid interruption during severe fault-current events, helping protect conductors and connected equipment.
Its Curve D characteristic provides increased tolerance of high transient starting currents, making the P1MBUH2PD06 particularly useful for compatible transformers, power supplies, solenoids and other inductive loads. Combined with its 6 A rating, 480Y/277 V AC UL operational voltage and 10 kA short-circuit rating, it provides a robust two-pole solution for industrial electrical protection.
Typical Applications
- Industrial electrical control panels.
- UL489 branch circuit protection.
- 480Y/277 V AC industrial electrical systems.
- Industrial machinery and automation equipment.
- Compatible transformer, solenoid and power supply circuits with high inrush currents.
- OEM electrical control and distribution assemblies.
