Connectwell STH4DT – Screw Clamp Terminal Blocks – Stud / Bolt

Feature

Stud Type Terminal Block

These Terminal Blocks are preferred for applications where the connections are subjected to severe vibrations.The wire is crimped to ring /fork type Lug (Ferrule) and is screwed on to flat current bar on the Terminal Block. The fastening nut always remains captive in the hinged plastic carrier. The Hinged Carrier should be lifted to insert the lugs and then snapped back into position. The nut can then be fastened to complete the connection. By the virtue of the hinged design the Terminal Blocks apart from shrouding the live parts, providing IP20 protection, saves considerable time in wiring. STH4DT Disconnect & Test Terminal Block is used for measuring, control and regulatory circuits. They provide a clear functional advantage for devices having utility instruments and associated transformers. Seperate testing points facilitate insertion of test probes. Disconnection is achieved by means of slide link operated with a screwdriver.
