Description
MCB (Miniature Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are essential electrical protection devices used to automatically disconnect power during overload, short circuit, or fault conditions. They help prevent damage to electrical equipment, wiring, and reduce the risk of fire and electrical hazards.
MCBs are typically used in low-current applications such as residential and light commercial installations, offering fast and reliable protection. MCCBs are designed for higher current and industrial applications, providing adjustable trip settings, higher breaking capacity, and enhanced protection features.
Both MCB and MCCB breakers are designed for long service life, easy installation, and safe operation. They comply with international electrical standards and are widely used in distribution boards, control panels, and power systems.
