Residual current circuit-breakers, two-pole, 40 A, 0,50 A, Type A, for point heaters, N arbitrary

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. 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. 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 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 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.

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.
