What is a 100A 4 Pole MCB used for?
It is typically used in three-phase circuits for EV chargers, solar inverters, motors, and lighting systems that require high-current protection with full pole isolation.
Why use a C curve MCB?
C curve breakers are designed to handle higher inrush currents, making them suitable for motor loads, EV chargers, and circuits with equipment that draws more current at start-up.
Can this breaker be used as an isolator?
Yes. In addition to overload and short-circuit protection, the WKC4100C can also function as a manual isolator for maintenance and testing.
Does this product comply with UK standards?
Yes. It is tested and certified to BS EN 60898-1, meeting all requirements for use in UK electrical installations.
