Doepke Schaltgeräte GmbH is a well-known German manufacturer of low voltage switchgear products such as RCCBs, MCBs, MRCDs, Twilight Switches and supplier of MCCBs, RCBOs and Rail-mounted devices for more than 60 years.
Selftest: Automated function tests offer increased safety
Doepke's Selftest' series of intelligent residual current circuit-breakers perform a self-test at regular intervals. Whereas previously self-tests had to be activated manually by pressing the test button, these devices now do this automatically every 30 days. What's more there is a check to ensure that the switch is functioning properly. Bypass contacts provide the power supply to the system during these self-tests, and a programmable potential-free contact allows a log to be kept.
Dasy twilight switch
The Dasy twilight switch means connected consumers are switched on at the desired level of dusk, and off again when there is sufficient brightness. The twilight value is also easy to adjust thanks to the rotary knob, without the need for tedious programming or a special tool. The light is therefore always switched on at the right time, even as times of brightness change through the seasons.
DCTR residual current transformers for non-stop monitoring
Doepke's intelligent transformers as per DIN EN 62020 are a retro-fittable solution for indicating residual currents via an integrated 4–20 mA interface. This makes it possible to directly evaluate the current residual current in the system being monitored. An integrated relay is activated when the fixed limit value is exceeded, making it possible to trigger a pre-alarm or, if used in combination with a circuit-breaker, to switch off the affected part of the system.
