Residual current circuit breakers Type AC
• residual current circuit breakers with high and medium sensitivity, AC residual currents (alternating sinusoidal current),
• 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 conventional short-circuit current (Inc): the value depends on the rated current of the short-circuit protection protecting the residual current circuit breaker,
• optical actuation indicator (circuit breaker opening/closing and circuit breaker tripping due to differential current),
• wide range of accessoriesó
• possibility of connection using vertical and horizontal comb busbars,
• cage terminals:
- circuit breakers with a rated current of 16 ÷ 63 A: solid up to 25 mm2, stranded up to 16 mm2
- circuit breakers with a rated current of 80 ÷ 125 A: solid up to 50 mm2, stranded up to 35 mm2,
• degree of protection: IP2X for terminals, IP40 for the device built into the switchgear.
