Doepke FI protection switch 4p, 40 A, 0.3 A, type B +, for heat pumps, N-li

The power supply (RCCB) switches off when dangerous high error flows occur. They thus protect persons, animals and plants. DFS 4 series devices are a compact four-pole power control switch for one or three-phase networks. In the standard version, they only have four units. The all-current sensitive switches cover smooth simultaneous error flows as well as all other error flows according to DIN VDE 0664-400. The HP (Heat Pump) variant was specially developed for the protection of heat pumps. The protection level of the all-current sensitive error control switch meets all requirements of the heat pump manufacturers. In addition, the HP-optimized short-term delay ensures increased plant availability. Standard-version devices are designed for the monitoring of circuits with a measurement voltage of 230 V, 400 V and a measuring frequency of 50 Hz. Characteristics: all-current sensitive to error flows with frequencies and mixed frequencies from 0 Hz to 20 kHz, fire protection according to VDE 0100-420, full operation with power voltage of at least 50 V AC on two active conductors, high short circuit strength, two-side double-deck terminals for large cross-section and rail connection, switching display, multi-function control nebula with three positions: one, off, triggered, neutral conductor position of any kind, type of assembly: fast-fitting on the support rail, any installation, feed-in-up of the-line, industrial and TS- THP systems are preferably suitable for commercial applications of the NS- NS- and TS- type: where heat pumps are used. Note: suitable for use in 50-Hz AC networks, not suitable for use on the output side of controlled electrical equipment such as frequency converters.
