Why Choose the Lovato P1MBUH3PC30 Miniature Circuit Breaker?
The Lovato P1MBUH3PC30 is a compact and reliable three-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in industrial and commercial electrical systems. As part of the Lovato P1 MB miniature circuit breaker range, it combines a 30 A rated current with a C tripping curve for effective protection of circuits with moderate inrush currents.
Designed for applications requiring compliance with UL 489 as well as IEC requirements, the P1MBUH3PC30 is suitable for branch-circuit protection in machinery, control panels and electrical distribution equipment. Its thermal-magnetic operating principle provides protection against sustained overload conditions and rapid interruption of high short-circuit currents.
With a 30 A rated current, three-pole configuration, 480Y/277 V AC UL rated operational voltage and 10 kA short-circuit rating, the P1MBUH3PC30 provides robust protection while occupying only three DIN modules inside an electrical enclosure.

Reliable Three-Phase Circuit Protection
Miniature circuit breakers such as the Lovato P1MBUH3PC30 automatically interrupt electrical circuits when overload or short-circuit conditions occur. The thermal element responds to sustained overloads, while the magnetic mechanism provides rapid operation during severe fault-current conditions, helping protect conductors and connected equipment.
The C-curve characteristic makes the P1MBUH3PC30 well suited to general industrial circuits and equipment with moderate starting currents. Its three-pole construction enables simultaneous protection and switching of three-phase circuits, while DIN rail mounting simplifies integration into modern control panels and distribution assemblies.
Typical Applications
- Three-phase industrial branch circuits.
- Electrical control panels and switchboards.
- Industrial machinery and automation systems.
- General-purpose motor and inductive load circuits.
- Commercial and industrial power distribution.
- OEM machinery requiring UL 489 circuit protection.
