Our Range of Products

Need of Terminal / Requirement of Specific Block

Busbar-type Terminal Blocks are widely used in power and distribution panels, as larger cross-section wires are used in these panels as incomers. These incoming cables are basically power cables which energize the panel and control the entire load. Busbar type Terminals are required for connecting these large cross-section wires, These incoming cables are either copper or Aluminium cables and are crimped with Ring-type Lugs. These Lugged wires are connected to Terminal Blocks using the Nut & Bolt arrangement provided in the Terminal Block.

Design speciality of Terminal Blocks

The Current Bar of the Busbar Terminal Block is made up of highly conductive copper and is integrated into the body in such a manner that it can be easily mounted on DIN Rail inside the Panel. The Body / Housing of the Terminal Block is made up of Polyadime 6.6 material which is an engineering plastic, which not only holds the Terminal Block on the DIN Rail but also sustains the pull-out force acting on the Terminal Blocks due to these larges cross-section wires.
