The ABB GSH202A-C63/0.03 is a 2-pole, 63A, Type A, C-curve Residual Current Circuit Breaker with Overcurrent Protection (RCBO). This integrated protective device is designed for single-phase circuits (or two-phase circuits) where the highest level of protection is required. It combines the functions of a miniature circuit breaker (MCB) for overload and short-circuit protection, and a residual current device (RCD) for earth leakage protection, all in one compact unit. The key feature is its Type A sensitivity, which detects both sinusoidal AC residual currents and pulsating DC residual currents, making it essential for protecting circuits feeding modern electronic equipment that contains rectifiers or switch-mode power supplies.
