RCD 63A 30mA 4pole type A CDA463J

Residual Current Circuit Breakers Type A
• residual current circuit breakers with high and medium sensitivity, residual currents A (sinusoidal alternating and pulsating current with a DC component),
• rated operational voltage: 230/400 V AC - two-pole circuit breaker, 400 V AC - four-pole circuit breaker,
• rated operating differential current in the range from 10 mA to 500 mA,
• rated making and breaking capacity (Im): 1500 A,
• rated short-circuit current  conventional (Inc): the value depends on the rated current of the short-circuit protection protecting the residual current device,
• optical actuation indicator (circuit breaker opening/closing and circuit breaker tripping due to differential current),
• wide range of accessories,
• possibility of connection using vertical and horizontal comb busbars,
• cage terminals:
- circuit breakers with a rated current of 16 ÷ 63 A: wire up to 25 mm2, stranded wire up to 16 mm2
- circuit breakers with a rated current of 125 A: wire up to 50 mm2, stranded wire up to 35 mm2,
• degree of protection: IP2X for terminals, IP40 for the device built into the switchgear.
