Why Choose the Lovato P1MBUL3PD50 Miniature Circuit Breaker?
The Lovato P1MBUL3PD50 is a robust three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for industrial and commercial electrical circuits. As part of the Lovato P1MBUL UL 489 miniature circuit breaker range, it combines a 50 A rated current with D-curve tripping characteristics for circuits supplying equipment with relatively high starting or inrush currents.
Designed for applications requiring UL 489 branch-circuit protection, the P1MBUL3PD50 uses thermal-magnetic protection to respond to sustained overload conditions and high short-circuit currents. Its three-pole construction provides coordinated switching and protection across three conductors, making it suitable for machinery, automation panels and industrial electrical distribution systems.
With a 50 A rated current, three-pole configuration, 240 V AC UL rated operational voltage and 10 kA short-circuit rating, the P1MBUL3PD50 provides dependable protection in a compact DIN rail-mounted format.

Reliable Protection for High-Inrush Industrial Circuits
Miniature circuit breakers such as the Lovato P1MBUL3PD50 protect electrical conductors and connected equipment by automatically interrupting the circuit when overload or short-circuit conditions occur. Thermal protection responds to sustained overcurrents, while the magnetic trip mechanism provides rapid interruption during severe short-circuit faults.
The D-curve characteristic makes the P1MBUL3PD50 particularly suitable for selected applications where connected equipment can produce substantial temporary inrush currents during energisation. Its three-pole construction, 50 A rating and compact DIN rail format make it a practical protection solution for industrial machinery, automation equipment and electrical distribution assemblies.
Typical Applications
