MCB
MCB Miniature Circuit Breaker
KC2 is the second generation of Miniature Circuit Breaker developed by Sinava. The breaking capacity Icnis up to 10kA, compatible with full range of accessories.
KC2 protects the low voltage final distribution systems against overload and short circuit. KC2 can also function as control and isolation in the domestic, commercial and industrial electrical distribution systems.
As a Circuit Breaker Manufacturer, Sinava Energy offers a range of circuit breakers, including Miniature Circuit Breakers (MCBs), Molded Case Circuit Breaker (MCCBs), and Air Circuit Breakers (ACBs) for different electrical distribution requirements.
