Single-Pole High-Current Plugs and Sockets

Single-pole high-current plugs and sockets are detachable connecting elements with rated currents such as 500 A and 750 A that connect the phase, neutral and earth conductors of a power line with separate connectors. They are used in applications such as generators, load banks, mobile distribution panels and temporary power supplies, where large-cross-section single-core cables are frequently disconnected and reconnected. The category includes TP Elektrik plug, extension socket, machine plug and machine socket types with IP67 protection, with 120 mm² screw or 300 mm² lug cable connection, and with housing colors of brown, black and gray for phases, blue for neutral and green for earth. Select the rated current according to the continuous load current of the line, the connection style according to the cable cross-section, the housing color according to whether the conductor is phase, neutral or earth, and the housing type according to whether the connection will be made at a cable end or on a panel. These connectors must not be confused with multi-pole plugs and sockets that carry 4 or 5 contacts in a single housing: here, a separate plug and socket pair is required for each conductor of a three-phase line.
