Doepke 09144814 DFS4 063-4/0,03-F EV residual current circuit breaker

Residual current circuit breakers (RCCB) switch off the power supply when dangerously high residual currents occur. They thus 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. Type F switches are mixed frequency sensitive. They protect against pulse and alternating residual currents as well as residual currents with mixed frequencies deviating from 50 Hz, regardless of the mains voltage. They are resistant to increased surge currents and storms. Switches in the EV version are intended for use in charging systems for electric vehicles. They have an additional function for detecting smooth DC residual currents >= 6 mA. They therefore protect upstream residual current circuit breakers of type A or F from malfunctions. Properties: sensitive to alternating and pulsating direct residual currents of mains frequency (type A) as well as alternating residual currents with mixed frequencies not equal to 50 Hz, mains voltage-dependent additional function for detecting smooth direct residual currents, tripping threshold of 6 mA for smooth direct residual currents, LED display for operation of additional function, no additional wiring required, validated, high immunity to surge residual currents and mains voltage-driven follow-on current pulses, small size for all rated currents, high short-circuit strength, double-sided double-deck terminals for large conductor cross-sections and busbar connections, switch position display, viewing window for labels, multi-function switch toggle with three positions: 'on', 'off', 'tripped', also available in the 'HD' version, connection C1 neutral conductor position on the left. Also available as N right at no extra charge, Mounting type: Quick fastening on mounting rail, Any installation position, Any feed direction, Areas of application: These RCCBs are intended exclusively for use in facilities for charging electric vehicles.
