PRCD-S pro from Kopp

Craftsmen often have to connect their tools on construction and assembly sites to sockets whose functional reliability they cannot check in advance. This can be dangerous because faults in the electrical installation cannot be detected immediately. The new PRCD-S pro series from Kopp guarantees safe power consumption even without prior testing.

With the PRCD-S pro, Kopp defines a new generation of portable fault current protection devices. The devices not only meet the requirements of VDE 0661 and the expectations of the professional associations, they also offer numerous other functions that make the mobile personal protection devices even safer for craftsmen and installers in their everyday lives. Heinrich Kopp GmbH has applied for a patent for these extensive extensions compared to the classic PRCD-S. The new PRCD-S is a new generation of the PRCD-S.

Now also switch on with gloves

The previous PRCD-S requires direct skin contact to switch on, so that the protective conductor can be correctly checked during the switch-on process. The new PRCD-S pro series from Kopp can now also be operated with gloves and insulating work shoes.

After switching on, the PRCD-S pro checks whether the protective conductor (PE) is properly connected and free of external voltage. In addition, the device checks the quality of the protective conductor and can only be switched on if the resistance value of the protective conductor (PE) is sufficiently low. The PE resistance is also continuously checked during operation. If the protective conductor is damaged or interrupted during operation, the PRCD-S pro switches off for safety reasons.

Self-test ensures safety

Also new is the self-test of the PRCD-S pro: The fault current circuit is automatically checked every time it is connected to the socket and every two hours of operation. The switching contacts of the devices are also continuously monitored. These functions meet the requirements for maximum safety.

On construction sites, machines are often operated which have to be controlled in their working speed. These speed adjustments are made, among other things, with the aid of frequency converters. In the event of a fault, these devices generate smooth DC fault currents in addition to the 50 Hz AC and pulse DC fault currents. In contrast to conventional type A protective devices, the PRCD-S pro also detects smooth DC residual currents.

All PRCD-S pro devices from Kopp are offered with IP67 protection.
