Residual current circuit breakers (RCCB) switch off the power supply when dangerously high residual currents occur. In this way, they protect people, animals and systems. DFS 4 are two- or four-pole residual current circuit breakers for single- or three-phase networks. In the standard version, the compact devices are four division units 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. AC type switches only detect alternating residual currents. In Germany, they are therefore not approved as residual current protection devices. Residual current circuit breakers in W version are optimized for switch heaters. They have a rated frequency of 16 2/3 Hz for railway systems up to 500 V. Properties: - two-pole version (4 TE) with two integrated auxiliary switches (2 S) - three-pole version (4 TE) with one integrated auxiliary switch (1 S) - tripping independent of mains and auxiliary voltage, - sensitive to alternating residual currents (type AC) - small size for all rated currents, - high short-circuit strength, - double-sided double-deck terminals for large conductor cross-sections and rail connection, - switch position indicator, - viewing window for labels, - multifunctional switch toggle with three positions: 'on', 'off', 'tripped', - also available in the 'HD' version - neutral conductor position as desired Mounting type: - quick fastening on mounting rail - installation position as desired - feed direction as desired Areas of application: - preferably in earthed power grids for railways to protect the switch heating systems, - use in TN-C grids and for Protection of systems in which electronic equipment can cause smooth DC residual currents. Notes: - The use of AC type residual current circuit breakers is not permitted in all countries. Observe the relevant national installation regulations.
