The PTV terminal block series with side wire entry connection combines the clarity of screw connection with the ease of push-in connection. This enables clearer wiring and eliminates bending of wires in confined spaces. The design also allows for clearer marking of both the terminal block and wire. This series features feed-through, three-conductor (-TWIN) and four-conductor (-QUATTRO) terminal blocks. Testing and bridging options are available on each terminal block. Disconnect and knife disconnect terminal blocks also are available. The tool-free push-in connection technology provides time-saving wiring.
