The CHINT NXB-63H 4 POLE Miniature Circuit Breaker is a protective device used in electrical systems to safeguard against overcurrents and short circuits. This model is a 4-pole breaker, designed to protect four conductors simultaneously, commonly used in three-phase electrical systems with a neutral wire. Like other MCBs, it interrupts the electrical circuit when it detects a fault, preventing damage to wiring and equipment. The NXB-63H is part of CHINT's line of circuit protection devices and is widely used in commercial and industrial electrical installations where three-phase power distribution with a neutral is required.
