Why Choose the Lovato P1MBUL2PD50 Miniature Circuit Breaker?
The Lovato P1MBUL2PD50 is a robust two-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for industrial branch circuits. Part of the Lovato P1 MB series, it combines thermal-magnetic protection with a D tripping characteristic for circuits where relatively high starting or inrush currents can occur.
Designed for industrial control panels, distribution equipment and machinery, the P1MBUL2PD50 provides a 50 A rated current and a 10 kA short-circuit rating. Its two-pole construction enables simultaneous circuit isolation, while the D-curve characteristic is suited to appropriately engineered loads that can produce substantial short-duration inrush currents.
With a 240 V AC rating under UL 489, the P1MBUL2PD50 provides dependable branch-circuit protection in compatible electrical systems. Its modular construction and standard DIN rail mounting allow straightforward integration into industrial electrical panels, distribution boards and machine-control assemblies.

Reliable Protection for Industrial Circuits
Miniature circuit breakers such as the Lovato P1MBUL2PD50 automatically disconnect a protected circuit when excessive current results from an overload or short circuit. Thermal operation provides protection against sustained overload conditions, while the magnetic mechanism provides rapid interruption when a severe fault current occurs.
The D tripping characteristic is intended for suitable circuits where temporary starting currents can be considerably higher than normal operating current. Combined with its 50 A rating, two-pole construction, 10 kA short-circuit capability and UL 489 compliance, the P1MBUL2PD50 provides dependable protection for demanding industrial electrical installations.
Typical Applications
- Industrial branch-circuit protection.
- Electrical control panels and distribution boards.
- Industrial machinery and automation equipment.
- Circuits with relatively high starting or inrush currents.
- OEM machine-building electrical assemblies.
- Industrial power and control installations.
