Why Choose the IMO B10C4002A Miniature Circuit Breaker?
The IMO B10C4002A is a high-quality four-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for three-phase electrical systems with a switched neutral. As part of the trusted IMO B10 Series, it combines a compact modular design with a 10 kA breaking capacity, making it ideal for industrial automation, commercial installations and OEM electrical equipment.
With a 2 A rated current and a C curve tripping characteristic, the B10C4002A is intended for low-current circuits that experience moderate inrush currents, such as control systems, instrumentation, transformers and auxiliary equipment. Its thermal-magnetic operating mechanism delivers reliable protection against sustained overloads while providing rapid interruption during short-circuit faults.
The breaker is designed for installation on a standard 35 mm DIN rail and simultaneously switches all four poles, ensuring complete isolation of three-phase circuits when required. Manufactured in accordance with IEC 60898-1, it provides dependable long-term protection for demanding electrical applications.
