£274.20
The Lovato P1MBUL3PC63 is a robust three-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. Part of the established Lovato Electric P1MB series, it combines thermal and magnetic protection within a compact DIN rail-mounted device suitable for machinery, control panels and electrical distribution systems.
Featuring a rated current of 63 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL3PC63 provides dependable protection for higher-current circuits supplying equipment with moderate starting currents. Typical applications include motors, transformers, contactors, power supplies and other inductive electrical loads.
The circuit breaker has a three-pole configuration and occupies three DIN modules, enabling all three protected conductors to be disconnected together when a fault occurs. Its 230/400 V AC IEC rating, 240 V AC UL rating and compliance with IEC/EN 60947-2 and UL 489 support use in industrial equipment and internationally specified installations.
The Lovato P1MBUL3PC63 uses a thermal-magnetic operating mechanism to provide two complementary forms of electrical protection. The thermal element responds to sustained overload currents, while the magnetic element rapidly disconnects the circuit when a high short-circuit current is detected.
Its Type C response characteristic allows the circuit breaker to tolerate moderate temporary inrush currents without unnecessary tripping. This makes it suitable for industrial circuits supplying motors, transformers, contactors, solenoids and power supplies while maintaining dependable protection during electrical faults.
