Why Choose the Lovato P1MBUH3PD01 Miniature Circuit Breaker?
The Lovato P1MBUH3PD01 is a compact three-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial and commercial electrical circuits. As part of the Lovato P1MBUH UL 489 circuit breaker range, it combines a low 1 A rated current with D-curve tripping characteristics for circuits containing equipment with comparatively high starting or inrush currents.
Designed for applications requiring UL 489 branch-circuit protection, the P1MBUH3PD01 uses thermal-magnetic protection to respond to both sustained overloads and short-circuit faults. Its three-pole construction enables simultaneous protection of three conductors, making it suitable for machinery, control systems and electrical distribution equipment.
With a 1 A rated current, three-pole configuration, 480Y/277 V AC UL rated operational voltage and 10 kA short-circuit rating, the P1MBUH3PD01 provides a practical DIN rail-mounted solution for low-current industrial circuits requiring robust branch-circuit protection.

Reliable Protection for Low-Current Industrial Circuits
Miniature circuit breakers such as the Lovato P1MBUH3PD01 protect conductors and connected equipment by automatically interrupting the circuit when excessive current occurs. Thermal protection responds to sustained overload conditions, while the magnetic trip mechanism reacts rapidly to high short-circuit currents.
The D-curve characteristic is particularly useful where normal equipment energisation can produce a substantial temporary current increase. Combined with its three-pole construction and low 1 A rating, the P1MBUH3PD01 is well suited to selected control, automation and industrial circuits where high inrush tolerance and branch-circuit protection are required.
Typical Applications
- Low-current industrial branch circuits.
- Three-phase control and auxiliary circuits.
- Industrial machinery and automation equipment.
- Loads with comparatively high energisation or inrush currents.
- Electrical control panels and distribution assemblies.
- OEM machinery requiring UL 489 circuit protection.
