Residual current circuit-breakers, four-pole, 16 A, 0,03 A, Type A, with emergency shut-off function, 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 A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Push-buttons for disconnection in emergency situations can be connected to residual current circuit breakers in the NA design (NA for emergency switching off). An integrated LED indicates the emergency tripping by a push-button or wire break. The residual current circuit breaker can be reactivated once the fault has been rectified. Several RCCBs can be connected in parallel.

tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A) , Only 1/2 module width wider than standard device, No additional power supply required for emergency switching off circuit, Full range of emergency switching off function, 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 top

NA series RCCBs are especially suitable for systems where an emergency switching off circuit with disconnecter properties is required, e.g. in teaching rooms or production facilities, 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+).
