Details
Residual current circuit-breakers, four-pole, 40 A, 0,03 A, Type A, high temperature 75°C, N left, HD
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 A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. RCCBs in the HT version have been specially developed for use in installations with higher ambient temperatures of up to 75 °C. With an airtight, encapsulated tripping mechanism from a special alloy and the stainless steel latch, residual current circuit-breakers in HD design are protected, in particular from corrosion, corrosive gases, moisture and extreme temperature fluctuations.
quick fastening to mounting rail, any installation position, supply from any direction
