Certain Application in Control and Measurement circuits necessitate locating operating faults quickly without disconnecting the conductors. elmex offers a range of disconnecting type terminal blocks which can be used to disconnect the continuity without actually removing the wires. KULTD 4: These Terminal Blocks finds special application in control and instrumentation industry. The hinged knife edge lever can be easily pushed open to simulate faulty condition. The copper link and brass contacts are tin plated offering low contact resistance. KUTSD 6 / KUTD 10 : This terminal blocks mainly find applications in secondary circuit of CT, Relay Panels etc. A clearly visible sliding link is used for disconnection. The link can be moved to one side by unscrewing. The tightening of the screw prevents it from sliding back. The 4 mm diameter nut assembly can be used as test sockets. KUTSD 6 offers feature of shorting two adjacent terminals using an internal removable shorting link, useful in SCADA applications.
