2-In 2-Out Test Terminal Blocks
A 2-in 2-out test terminal block is a multi-input DIN rail terminal block with two push-in connection points on each side and a knife disconnect mechanism in the middle. It is used in control and signal circuits during commissioning, periodic maintenance and fault finding to isolate the input and output sides and take measurements without removing conductors. In this category, Onka OPK series 2.5/4 mm² test terminal blocks are listed with 24 A rated current and 750 V rated voltage, in beige, gray, brown, red, blue, yellow, black and green. First determine whether the circuit needs to be isolated at the terminal block; compare the conductor cross-section with the 2.5/4 mm² connection cross-section and the circuit current with the 24 A rated current, and choose the housing color by circuit grouping. It should not be confused with the measuring disconnect terminal block used in current transformer secondary circuits; for those circuits, the types in the Measuring and Disconnect Terminal Blocks category are used.
