Residual current circuit-breakers 2-pole, 100 A, 0.03 A, Type A, N arbitrary

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 2 are two-terminal residual current circuit-breakers for single-phase networks. In the standard design, the compact devices are just two module widths wide. The compact residual current circuit-breakers are available with a number of different types of residual currents and versions at rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. A practical multifunction switch toggle simplifies troubleshooting. They can be provided with pre-prepared labels using free-of-charge software. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Devices in the standard design are intended for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: 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"; also available in the "HD" design; Neutral conductors with standard design left, for two-terminal-pair devices type A/AC/F up to 125 A and type B/B+ up to 80 A; N-right available at no extra charge.; Mounting: quick fastening to mounting rail; any installation position; supply from any direction; Application areas: Power supplies to residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks. the residual current circuit-breakers of this series can be set to switch off in the event of a second fault.; Excluded is the application in TN-C systems and for the protection of installations in which electronic equipment could generate smooth DC currents or residual currents with frequencies other than 50 Hz. Comprehensive protection is not provided in this case. For these applications we recommend our AC/DC sensitive residual current circuit-breakers (Type B or B+).;
