Connectwell 4 sq.mm Spring Loaded Feed Through Terminal Blocks

These modified version of feed through Terminal Blocks come with springs below the clamps. These Terminal Blocks are preferred for connections that involve safety requirements of the Electric Supply Industry (ESI) standards, British CEGB regulations and NTPC applications. In addition to the high torque screws, these blocks have a built-in spring loading feature.

It is recommended to use hook type lug / ferrule for terminating wires in such connections.

These Terminal Blocks have a specially designed current bar for the right location & placement of wires crimped in hook type lug / ferrule, thus preventing loosening of the wires even when the screw clamps are not tightened.
