Auxiliary switch for DRCBO 3, DAFDD 1, ELS 3, 250 V, 4 A, 2 CO

Auxiliary switches report the status of the main devices to which they are fitted. The DHi 12 auxiliary switch can be retro-fitted on a residual current operated circuit-breaker with integral overcurrent protection from series DRCBO 3, on the arc-fault detection device DAFDD 1 as well as on miniature circuit-breakers from series ELS 3. The DHi 12 makes it possible to indicate the operating conditions of a residual current circuit-breaker by using additional output devices, e.g. buzzers or indicator lights. The function is set via a control element on the DHi. It signals the switch-on and switch-off of the RCCB in "auxiliary switch" operating mode; only tripping is signalled in "error signal switch" operating mode.

auxiliary switch or fault signalling switch function, retro-fittable, compact design

snaps on the main device to the left of the basic device, quick fastening to mounting rail, any installation position

These devices are suitable for querying the operating status of power supplies to residential and purpose-built buildings as well as to industrial facilities.

The auxiliary switch does not affect the function of the basic device.
