ETS1E MCCB
ETS1E MCCB (Moulded Case Circuit Breaker) is a high-capacity circuit protection device designed for industrial and high-demand residential applications. It provides reliable protection against overloads and short circuits, and can also function as a main switch or isolator. With a rated current range of 100A to 800A and a breaking capacity between 10kA and 35kA, MCCBs are ideal for systems where standard MCBs are insufficient. They are commonly used in main distribution boards, capacitor banks, generators, and primary power feeders.

ETS1E MCCB is the short form of Molded Case Circuit Breaker. It is the circuit breaker used when the loaded current is higher than the limit of a MCB. MCCB is an electrical protection device which has the same protection of MCB. It is used for protection against overload and short circuit faulse, and can be also used as an isolator or main switch. It is mainly used in industrial applications and higher current rating and fault level residential applications, because its wide rated current and high breaking capacity. MCCB can be used to offer protection for the capacitor bank, generator and main electric feeder distribution.
