Residual current circuit breakers (RCCB) disconnect the power supply when dangerously high fault currents occur. They protect people, animals, and installations. Devices from the DFS series are compact four-pole residual current circuit breakers for single-phase or three-phase networks. In the standard version, they occupy only four division units. The all-current sensitive switches detect smooth direct fault currents as well as all other fault currents according to DIN VDE 0664-400. The PV variant has been specifically developed for use in photovoltaic systems and offers the highest level of protection for this purpose. With a PV-optimized short-time delay, the all-current sensitive residual current circuit breaker is resistant to surge currents, providing higher system availability due to fewer false trippings. 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.

Features:

• All-current sensitive for fault currents with frequencies and mixed frequencies from Hz to 20 kHz
• Fire protection according to VDE 0100-420
• Full functionality with network voltages of at least 50 A
• Can be connected to any two active conductors
• High short-circuit resistance
• Double-decker terminals on both sides for large conductor cross-sections and rail connection
• Switching position indicator
• Multifunctional switch knob with three positions: "on," "off," "tripped"
• Neutral conductor position is arbitrary
• Mounting type: Quick fastening on mounting rail
• Installation position is arbitrary
• Preferred feed from above

Areas of application: RCCBs of the PV variant are suitable for private, commercial, and industrial installations with TN-S, TT, and TN-C-S systems where photovoltaic systems are installed.

Notes:

• Suitable for use in 50 Hz alternating current networks
• Not suitable for use on the output side of controlled electrical equipment such as frequency converters.
