Knife Disconnect System Terminal Blocks
A knife disconnect system terminal block is a screw-connection DIN rail terminal block that isolates the circuit without removing conductors, using a hinged knife contact in its housing. It is used in control, signal and measuring circuits to open the line temporarily and take measurements during commissioning, testing and fault finding. In this category, Onka MRK series 2.5/4 mm² and 6 mm² knife disconnect system terminal blocks are sold per piece with gray and beige housings and a 750 V rated voltage. Choose the housing (2.5/4 mm² or 6 mm²) by conductor cross-section, the terminal block's rated current by the circuit current and the housing color by grouping in the terminal block row; verify under which conditions the knife may be opened from the manufacturer data. A knife disconnect terminal block does not replace a switch or load break switch; it is used to isolate for testing and measurement purposes.
