Residual current circuit breaker (RCCB) with auxiliary device Doepke

PRCDs are portable devices that are used for additional protection on existing electrical installations with unknown or insufficient protection. They combine residual current protection, undervoltage tripping and neutral conductor monitoring. If a protective conductor is also connected, they also offer protective conductor monitoring. Devices in the DPRCD-M series are base components for producing three-phase PRCD personal protection devices. They are suitable for DIN rail mounting and are compatible with housings of leading manufacturers. The devices combine an AC-DC sensitive residual current device with network and protective conductor monitoring, and measure just 8 module widths. Thanks to 6-mA-DC detection, the device also ensures the protective function of upstream residual current circuit breakers. Type B PRCDs are to AC/DC for residual currents from 0 Hz. They have increased resistance to surge currents and lightning. Properties: Base component for setting up a PRCD; Includes residual current detection, undervoltage tripping, network and protective conductor monitoring; Tripping threshold of 6 mA for smooth DC residual currents; High short circuit resistance; double-sided two-tier terminals for large conductor cross-section and busbar; Switch position indicator; Viewing window for labels; Multifunctional knob with three positions: ‘On’, ‘Off’, ‘Tripped’; Mounting: quick fastening to mounting rail; any installation position; supply from top; Application areas: PRCDs are used in mobile applications in which the protective measure of the upstream electrical installation is unknown or insufficient, e.g. on construction sites. at events or during rescue operations. Hints: DPRCD-M is the base component of a three-phase PRCD. The housing is not included in the scope of delivery. DPRCD-M is compatible with many housings from leading manufacturers.
