Why Choose the Lovato P1MBUL3PD40 Miniature Circuit Breaker?
The Lovato P1MBUL3PD40 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 P1 MB miniature circuit breaker range, it combines a 40 A rated current with a D tripping curve for circuits supplying equipment with relatively high starting or inrush currents.
Designed for applications requiring UL 489 branch-circuit protection while also complying with IEC/EN 60947-2, the P1MBUL3PD40 provides dependable protection in a compact modular format. Its three-pole construction enables coordinated switching and protection of three conductors, making it suitable for machinery, automation panels and industrial electrical distribution systems.
With a 40 A rated current, three-pole configuration, 240 V AC UL rated operational voltage and 10 kA short-circuit rating, the P1MBUL3PD40 delivers effective circuit protection while occupying only three DIN modules inside an electrical enclosure.

Reliable Protection for High-Inrush Industrial Circuits
Miniature circuit breakers such as the Lovato P1MBUL3PD40 automatically interrupt electrical circuits when overload or short-circuit conditions occur. This helps protect conductors and connected equipment against damaging overcurrents while providing a convenient means of isolating the protected circuit.
The D-curve characteristic makes the P1MBUL3PD40 particularly suitable for selected applications where connected equipment can produce substantial temporary inrush currents during energisation. Its three-pole construction, 40 A rating and compact DIN rail format make it a practical protection solution for industrial machinery, automation equipment and electrical distribution assemblies.
Typical Applications
- Three-pole industrial branch circuits.
- Industrial machinery and automation equipment.
- Circuits supplying loads with high starting or inrush currents.
- Electrical control panels and distribution assemblies.
- Commercial and industrial electrical systems.
- OEM machinery requiring UL 489 branch-circuit protection.
