The ABB 2CSR255180R2324, also known as the DS203M C32 A100, is a premium residual current circuit breaker with overcurrent protection (RCBO) designed to provide comprehensive protection for three-phase electrical installations. Combining earth leakage, overload and short-circuit protection in one compact device, it helps improve electrical safety while reducing the number of components required within distribution boards.
Part of the trusted ABB System pro M compact DS203M series, this RCBO features a 3P+N configuration with protection on all three phase conductors. It is suitable for commercial buildings, industrial control panels, machinery, distribution boards and infrastructure projects where dependable protection is essential.
With a rated current of 32 A, a C tripping characteristic and a rated residual operating current of 100 mA, the DS203M C32 A100 provides reliable protection against earth leakage and overcurrent faults while supporting standard 400–415 V AC three-phase systems.
Key Advantages
