Doepke 09124601 DFS2 025-2/0.03-A 2-pole 25/0.03A residual current circuit breaker

Residual current circuit breakers (RCCBs) switch off the power supply when dangerously high residual currents occur. They thus protect people, animals and systems. DFS 2 are two-pole residual current circuit breakers for single-phase networks. In the standard version, the compact devices are two modules wide. They are available with many different residual current types and versions with rated currents of up to 125 A. The large double-deck terminals can also accommodate large conductor cross-sections. The tripped position of the multi-function switch toggle makes troubleshooting easier. The free label software helps with labeling. Type A switches are sensitive to pulse and alternating current. This function is independent of the mains voltage. Devices in the standard version are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: - tripping independent of mains and auxiliary voltage, - sensitive for alternating and pulsating direct residual currents (type A) - small size for all rated currents, - high short-circuit strength, - double-sided double-deck terminals for large conductor cross-sections and rail connections, - switch position indicator, - viewing window for labeling labels, - multifunctional switch toggle with three positions: 'on', 'off', 'tripped', - also available in the 'HD' version - any neutral conductor position Mounting type: - quick fastening to mounting rail - any installation position - any feed-in direction Areas of application: - power supplies for residential and commercial buildings as well as industrial plants with TN-S, TT and TN-CS networks. In IT networks, residual current circuit breakers from this series can be used to switch off in the event of a second fault. - They cannot be used in TN-C networks or to protect systems in which electronic equipment can cause smooth DC residual currents or residual currents with frequencies other than 50 Hz. Comprehensive protection is not provided here. For such applications, we recommend our universal current sensitive residual current circuit breakers (type B or B+).
