Carlo Gavazzi has expanded their already comprehensive range of three-phase monitoring relays to include the DPB71 and the DPC Series. These are three phase devices which are ideal for protecting machinery and people in instances where three phase voltage is used, such as with industrial automation machinery, switchgear and elevators/escalators.

The DPB71 Series is constructed i... (read more)

Carlo Gavazzi has announced the introduction of the DPA53 Series, a new phase monitoring relay with relay output, which detects: under-voltage, and improper phase sequence or phase loss. (read more)
