£295.55
The Lovato P2MB4PC100 is a robust four-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. As part of the dependable Lovato P2MB series, it combines high-current circuit protection, positive contact indication and convenient DIN rail installation for modern distribution boards, switchboards and control panels.
This circuit breaker features a C characteristic tripping curve, making it suitable for circuits with moderate inrush currents, including lighting systems, control equipment, small motors and general industrial loads. Its four-pole configuration enables simultaneous switching and protection of three phase conductors and a neutral conductor.
With a rated current of 100 A, a 230/400 V AC operational voltage and a 10 kA short-circuit breaking capacity, the P2MB4PC100 delivers dependable protection for demanding electrical installations. Its modular design and standard DIN rail mounting help simplify panel assembly, maintenance and replacement.
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. This helps protect conductors, connected equipment and electrical installations from damage caused by overloads and short circuits.
The four-pole configuration of the Lovato P2MB4PC100 makes it particularly suitable for three-phase systems in which the neutral conductor must be switched together with the phase conductors. Its C curve response provides reliable protection while tolerating the moderate starting currents associated with many industrial and commercial loads.
