Circuit Breakers
EV-Tronix carries LS Electric Circuit Breakers. Miniature Circuit Breakers (MCBs) are placed directly above the load and are designed to protect final loads. They are ideal for protection of circuits in industrial, commercial, and residential sectors, and ensures the following functions: protection against short-circuit and overload currents, isolation, and protection against indirect contact. LS Electric Molded Case Circuit Breakers (MCCB) are designed to protect low voltage electrical systems from overloads and short circuits.
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent or short circuit by automatically interrupting the flow of electricity when a fault is detected.
