Live Electrical CB350D 3 Pole 50A D Curve 10kA MCB
The Live Electrical CB350D 3 Pole 50A D Curve 10kA MCB is a bi-directional miniature circuit breaker designed for three-phase electrical distribution. Featuring a 50A current rating and 10kA breaking capacity, this device provides overcurrent and short-circuit protection in commercial and industrial installations.
Features and applications
The D curve tripping characteristic makes the CB350D suitable for selected circuits with high starting currents, including motors, transformers and other inductive equipment. Its three-pole configuration provides coordinated circuit protection, while the compact 54mm width allows installation within suitable distribution boards using a standard 35mm DIN rail.
With a rated operational voltage of 230/400V AC and an IP20 protection rating, this MCB is designed for use in appropriate electrical enclosures. Selection must account for prospective fault current, starting characteristics and required disconnection times.
