Residual current circuit-breakers, four-pole, 16 A, 0,03 A, Type A, Twin-Ausführung, kurzzeitverzögert, 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. The Twin design enables a function test of the residual current circuit-breaker without switching off the load circuit. Two complete RCCBs are combined in this design: If both devices are on, a switch can be tripped using the test button. The second RCCB takes over the current conduction and protective function. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Residual current circuit-breakers in the KV design have a response delay, so are much less sensitive to brief pulsed fault currents. This enables them to increase system availability. They can effectively be used instead of a standard switch, as their protective function is completely retained.

function test for residual current circuit-breaker without interrupting power, residual current protection complies with standard even during testing procedure, no costs during system downtime, high system availability , high immunity against surge currents and mains-voltage-operated secondary current impulses , 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"

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

Power supplies to residential and purpose-built building as well as industrial facilities with TN-S, TT and TN-C-S networks, in which conventional RCCBs trip following transient leakage currents and this is not desired, such as in systems with long cable lengths behind the RCCB, lighting systems with lots of fluorescent lamps (> 20 lamps), computer systems and solar power systems, The twin design allows regularly prescribed function tests to be performed without disconnecting the power, 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.
