Residual current circuit breakers (RCCB) disconnect the power supply when dangerously high fault currents occur, thus protecting people, animals, and installations. The DFS series devices 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 HP Heat Pump variant has been specifically developed for the protection of heat pumps. The protection level of the all-current-sensitive residual current circuit breaker meets all requirements of heat pump manufacturers. Additionally, the HP-optimized short-time delay ensures increased system availability. Devices in standard configuration 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 AC on any two active conductors
• High short-circuit resistance
• Double-deck 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 feeding from above

Areas of application: RCCB of the HP variant are suitable for private, commercial, and industrial installations with TN-S, TT, and TN-C-S systems where heat pumps are used.

Notes:

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