EJB and EJBX control panels are based on explosion-proof EJB and EJBX enclosures. EJB and EJBX panels are equipped with elements for switching, control and indication of operating modes of electrical circuits of alternating and direct current of industrial frequency.
The EJB and EJBX control panel is made to order. To place an order, it is necessary to fill out and send the manufacturer a questionnaire, which contains only general information on the order, as well as information about the customer. The production of control posts begins after the design project is agreed upon by the customer and the manufacturer. The customer chooses the type of cable glands, their number, as well as switching elements, indication, text inscriptions. Depending on the free space inside the housing, two types of terminal clamps are installed, screw or spring. Each switching element has one or two contacts. Normally closed and normally open contacts can be used. The manufacturer reserves the right to arrange all elements according to his project.
