The EJB and EJBX control panels are built using explosion-proof EJB and EJBX enclosures. The EJB and EJBX panels are equipped with switching, control, and indication elements for the operating modes of AC and DC electrical circuits at industrial frequency.
EJB and EJBX control panels are made to order. To place an order, you must complete and send the manufacturer a form containing general order information and customer details. Control station production begins after the design project has been approved by the customer and manufacturer. The customer selects the type and number of cable entries, as well as the switching elements, indicators, and text labels. Depending on the available space inside the enclosure, two types of terminal clamps—screw or spring-loaded—are installed. Each switching element has one or two contacts. Normally closed and normally open contacts can be used. The manufacturer reserves the right to configure all components according to its design.
