Stand A71 at PPMA 2018 (25-27 September) sees WAGO launch two variants of its TOPJOB® S family of rail-mounted terminal blocks.
A push-button version and a lever-actuated version, the first terminal block of its kind, gives switchgear manufacturers a wider choice for wiring assemblies, with three different wiring options within the same product range.
The clamping point of the push-button terminal block is opened with any screwdriver or similar operating tool. Feed-through terminal blocks with push-buttons are available for wire with a cross-section between 0.14 to 25 mm². The push-button terminal block is available in 2-, 3- or 4-conductor variants.
The lever-actuated variant, a world first from WAGO, is equipped with a lever on the field side, and a push-button or operating tool-actuated connection on the secondary side. The clamping point on the field side is opened and closed by hand using the lever, allowing installers to tell at a glance which wires in an assembly are terminated. Both the push button and lever actuators are orange in colour, making them clearly visible for easy identification.
The lever can be left open, freeing both hands to connect difficult-to-bend conductors with large cross sections. Versions are available for nominal cross-sections of 2.5 mm², 6 mm² and 16 mm², and in 2- or 3-conductor configurations.
All TOPJOB S rail mounted terminal blocks feature Push-In CAGE CLAMP® spring pressure connection. This is 50 percent quicker to wire compared to screws, free from maintenance and immune to loosening over time due to vibration or heat cycling. It also allows push-in connection of solid, seven strand and ferruled conductors.
