£230.58
The ABB DS203NC C32 A30 is a high-performance 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect three-phase electrical installations against overloads, short circuits and earth leakage faults. As part of the trusted ABB System pro M compact range, it combines the functions of an MCB and RCD into a single compact device, helping to simplify panel design whilst improving electrical safety.
Featuring a C curve tripping characteristic, 32 A rated current and 30 mA Type A residual current protection, the DS203NC C32 A30 is ideal for commercial, industrial and infrastructure applications where reliable protection against overload, short-circuit and residual currents is essential.
Its compact four-module design, high-quality construction and compliance with international standards make it suitable for distribution boards, machinery, control panels and industrial power systems requiring dependable circuit protection.
The ABB DS203NC C32 A30 delivers comprehensive protection by combining overload, short-circuit and earth leakage protection within a single device. This simplifies electrical panel layouts whilst ensuring compliance with modern installation requirements for commercial and industrial applications.
Its Type A residual current detection allows the device to detect both alternating residual currents and pulsating DC residual currents, making it suitable for circuits supplying modern electronic equipment, machinery and automation systems.
