Residual current circuit-breakers, four-pole, 63 A, 0,03 A, Type A, 150 Hz ... 400 Hz, N right
Function:
Type A residual current circuit-breakers detect pulsating direct current and alternating current. RCCBs in the Hz design are intended for rated mains frequencies other than 50 Hz. The frequency range for tripping current detection remains unaffected by this. Devices in the standard design are intended for circuits with a rated voltage of 230 V or 400 V.
Features:
tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A) , compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position right
Mounting method:
quick fastening to mounting rail, any installation position, supply from any direction
Applications:
Power supplies to TT, TN-S and TN-C-S networks with mains frequencies > 50 Hz, Not permitted for use in TN-C networks and for protecting systems in which electronic equipment may cause smooth DC residual currents or residual currents with frequencies not equal to 50 Hz. Comprehensive protection is not provided with an RCCB Type A. For these applications we recommend our residual current circuit-breakers Type F or our AC/DC sensitive residual current circuit-breakers Type B/B+.
