Why Choose the Lovato P1MBUH3PC25 Miniature Circuit Breaker?
The Lovato P1MBUH3PC25 is a robust three-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. As part of the dependable Lovato Electric P1MB series, it combines thermal and magnetic protection within a compact modular device suitable for machinery, control panels and electrical distribution equipment.
Featuring a rated current of 25 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUH3PC25 is well suited to circuits supplying equipment with moderate starting currents. Typical loads include motors, transformers, contactors, power supplies and other inductive electrical equipment.
The circuit breaker has a three-pole configuration and occupies three DIN modules, enabling all three phases to be disconnected together when an electrical fault occurs. Compliance with IEC/EN 60947-2 and UL 489 supports its use in industrial installations, OEM machinery and internationally specified control systems.

Reliable Protection for Three-Phase Electrical Circuits
The Lovato P1MBUH3PC25 uses a thermal-magnetic operating mechanism to provide two complementary forms of protection. Its thermal element responds to sustained overload currents, while the magnetic element rapidly disconnects the circuit when a high short-circuit current is detected.
The Type C response characteristic enables the breaker to tolerate moderate temporary inrush currents without unnecessary tripping. This makes it suitable for many industrial loads, including small motors, transformers, contactors, solenoids and control-system power supplies.
Typical Applications
- Industrial electrical control panels.
- Three-phase machinery circuits.
- Motor starters and automation equipment.
- Transformers and inductive loads.
- Manufacturing and processing machinery.
- Commercial electrical distribution boards.
- OEM machine-building projects.
- Control power and auxiliary circuits.
