Residual current circuit-breakers, four-pole, 40 A, 0,5 A, Type AC, for point heaters, with auxiliary switch, N left

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four module widths wide. They are available with many different residual current types and variants for rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. The trip position of the multi-function toggle switch simplifies fault-finding. The free label software helps in the labelling process. Type AC switches only detect AC residual currents. As a result, in Germany they are not approved as residual current operated protective devices. Residual current circuit-breakers in the W design are optimised for point heaters. They have a rated frequency of 16 2/3 Hz for track systems up to 500 V.

two-pole design (4 module width units) with two integrated auxiliary switches (2 S), three-pole design (4 module width units) with one integrated auxiliary switch (1 S) , tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents (type AC) , 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 left

quick fastening to mounting rail, any installation position, supply from any direction

preferably in earthed power networks for tracks used to fuse-protect point heater systems, 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.

The use of Type AC residual current circuit-breakers is not permitted in all countries. Pay attention to the corresponding national installation regulations.
