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.
The IMO B10C4002A combines thermal overload protection with instantaneous magnetic short-circuit protection to safeguard electrical installations against damaging fault conditions. Its four mechanically linked poles ensure all conductors are disconnected together, improving safety during maintenance and fault conditions.
The C curve operating characteristic is ideal for circuits supplying equipment with moderate starting currents, helping to minimise nuisance tripping while maintaining dependable protection. This makes the breaker suitable for industrial control panels, auxiliary supplies, instrumentation systems and low-current automation circuits.
