The Class 9001 Type KA contact blocks are Fingersafe® contact blocks (meeting VDE
0106 Part 100). They have one screw mounting and captive (backed out) plus/minus
terminal screws. These contact blocks are double-break, direct-acting contacts. Because
of the wiping action of these contacts, they are suitable for use with programmable
controllers. All contact blocks listed below accept up to 2 #12–#24 AWG solid or
stranded wires. Recommended tightening torque for screw terminals is 7 lb-in.
