Specialty Feed-through IEC Screw-type Terminal Blocks

Our Bulletin 1492 Specialty Feed-through IEC Screw-type Terminal Blocks have test plugs and adapters that identify the presence of voltage and perform simple diagnostic measuring of voltage. Feed-through terminal blocks are available with a test plug that breaks the circuit, forcing the current to run through a meter connected to the circuit-break test plug. Make-before-break or break-before-make test plugs can be used with the testing terminal block.
