Doepke 09134901HD RCCB A

Ground fault circuit interrupter (RCCB) switch off the power supply in case of dangerously high fault currents. Thus, you protect persons, animals and plants. DFS 4 are two or four pole ground fault circuit breakers for single or three phase networks. In standard design, the compact devices are four division units narrow. They are available with many different fault current types and versions at rated currents up to 125 A. The large double level terminals can also accommodate large conductor cross-sections. The trip position of the multifunction toggle facilitates troubleshooting. The free label software helps with the labeling. Type A switches are pulse- and AC-sensitive. This function is independent of mains voltage. Standard type devices are designed for monitoring circuits with a rated voltage of 230, 400 V, V and a rated frequency of 50 Hz. With an airtight sealed trigger in special alloy and the stainless steel switch lock, the fault-current circuit breakers in HD version are especially protected against corrosion, harmful gases, moisture and strong temperature fluctuations. Properties: Tripping independent of mains and auxiliary voltage; sensitive for alternating and pulsating DC fault currents (type A) small size for all rated currents; high short-circuit resistance; double-sided double-level terminals for large conductor cross-section and rail connection; switch position display; sight window for label labels; multi-function switching toggle with three positions: "On", "off", "triggered"; connection C1 neutral conductor position on left; mounting type: Mounting: Arbitrary; mounting position; Applications: power supplies for residential and commercial buildings and industrial systems with TN-S, TT and TN-C-S networks. In IT networks, fault-current circuit breakers of this series can be provided for shutdown in the event of a second fault; the use in TN-C networks and for the protection of plants is excluded. In which electronic equipment can cause smooth DC fault currents or fault currents with frequencies not equal to 50 Hz. There is no comprehensive protection here. For such applications, we recommend our all-current sensitive residual current circuit breakers (type B or B+).
