Disconnect & Test Terminal Blocks

These blocks are used for measuring, control and regulatory circuits. In CKT4U & CKT4U/4 disconnection is achieved by lifting a lever which operates the knife contact. Specially designed socket headed screws act as receptacles for test probes in these Terminal Blocks. CKT4U/S is another version of CKT4U Terminal Block in which regular slotted screws are used. CKT4SP terminal provides a possibility of using screw-type jumpers for cross-connection. CF4SPFT feed-through terminals have the same profile as that of the CF4SP and CKT4SP Terminal Block. CKT4SP series terminal is completely closed and does not need a separate endplate. CKT6U terminals have the same outer profile of CTS6U feed-through terminals. CKT4UH & CKT6U terminals have an extended tab on the disconnecting blade which facilitates the tool-less operation of the disconnecting contact. CKT6U terminal has the same profile as that of CTS6U & CTS10U feed-through terminals. The CDS6U 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. Separate testing points facilitate insertion of test probes. Disconnection is achieved using a slide link operated with a Screw Driver. In the CDS6U/TS, the insulated test point screw system (TPSLS) is integrated. CDS6U/FT Terminal Block is a standard feedthrough Terminal Block. In the CDS6U/SC Disconnect & Test Terminal Block, an additional safety spring is provided underneath the screw clamp. These Terminal Blocks are preferred for connections that involve safety requirements of the Electric Supply Industry (ESI) standards, British CEGB regulations and NTPC applications. The SLS2 and SLS4 sliding jumpers can be used in combination with either the supplied screw or the TPSLS Test point screw system. Lockout cap LCCDS can be used to lock the centre shorting screw, to prevent accidental opening of circuits.
