Electrical Connectors

Rota Engineering’s DR4 Connector is the first certified Ex de connector that may be disconnected with power on both sides and without the need for a hot-work permit. The DR4 incorporates features from the company’s DE2 (disconnect one side live) and the D3 (larger current disconnect both sides live) connectors. The ability to disconnect with both sides live allows for safe connection of Ex de circuits with stored energy and communication circuits such as Ethernet and Profibus with return protocol signals that were previously not possible in this compact size. The yellow visual marking around the connector body clearly signifies full engagement. The device enables quick connections of electrical circuits in hazardous atmospheres while eliminating the need for junction boxes and highly trained personnel.
