Live Electrical CB363C 3 Pole 63A C Curve 10kA MCB
The Live Electrical CB363C 3 Pole 63A C Curve 10kA MCB is a bi-directional miniature circuit breaker designed for suitable three-phase AC distribution installations. Combining a 63A current rating with a 10kA breaking capacity, it provides overload and short-circuit protection for commercial and industrial circuits requiring a C curve tripping characteristic.
Features and applications
The CB363C features a C curve thermal-magnetic tripping mechanism, designed to accommodate moderate starting currents. Its instantaneous magnetic trip characteristic typically operates between five and ten times the rated current, making it suitable for appropriately designed circuits supplying equipment with moderate inrush demands, including selected motors, transformers and inductive loads.
This three-pole circuit breaker provides linked switching across all three phases, allowing simultaneous disconnection. With a 54mm width, it occupies three standard DIN rail modules and mounts onto a 35mm DIN rail within compatible electrical distribution equipment.
Rated for 230/400V AC operation, the CB363C features IP20 protection and conforms to BS IEC/EN 60898. When specifying this 63A protective device, cable current-carrying capacity, prospective fault current, earth fault loop impedance and required disconnection times must be considered.
