PKV type-1, PKV type-2 PKV type-3, PKV type-4
The posts are intended for switching, controlling and indicating the operation modes of AC and DC electric circuits in the explosion hazardous areas. The posts are designed to connect armored and non-armored electrical cables of circular cross-section, as well as cables in metal hose or pipe.
As standard, the customer selects: the type of cable entries their number, as well as switching elements, indications, text labels. In view of the available space inside the case, terminal clamps of two types are screwed or spring-loaded. Each switching element has one or two contacts. Normally-closed and normally-open contacts can be used (see APPENDIX B, Table B1). The manufacturer reserves the right to arrange all elements according to his design.
Posts can have tablets with operational inscriptions in Russian and foreign languages: "Start", "Stop", "Forward", "Back", "Up", "Down", "Right" & " , "Left", "Fast", "Slowly", "Jog", "Brake", "Open", "Close", "Off", "Auto-0-On" and other short labels on the order of the consumer.
The posts are delivered with explosion-proof cable entries of the KV series TU 3449-138-81888935-2016 produced by OOO "SMD Company". The type, number and location of the cable glands is specified when ordering. Each cable entry is supplied with rubber seals for the cable.
