Details
Auxiliary switch for DRCBO 3, DAFDD 1, ELS 3, 250 V, max. 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.
