Why Choose the Lovato P1MB1NC04 Miniature Circuit Breaker?
The Lovato P1MB1NC04 is a dependable miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB series, it provides reliable thermal-magnetic protection for industrial control panels, commercial distribution boards and electrical automation systems.
Featuring a 4 A rated current, Type C tripping characteristic and 6 kA short-circuit breaking capacity, the P1MB1NC04 is suitable for low-current circuits that may experience moderate starting currents. Its protective mechanism helps safeguard conductors, control components and connected equipment from potentially damaging overcurrent conditions.
The breaker has a 1P+N configuration, providing overcurrent protection while switching both the phase and neutral conductors. Its two-module construction supports effective circuit isolation, while standard DIN rail mounting enables straightforward installation within modular electrical enclosures.
