The Class 9001 Type KA contact blocks have been improved. The most noticeable change is that the terminals are Fingersafe®
contact blocks (meeting VDE 0106 Part 100). They also have one screw mounting and captive backed out plus/minus terminal
screws. These contact blocks still use the same reliable double break direct acting contacts used since 1965. Because of the wiping
action of these contacts, they are suitable for use with programmable controllers. All contact blocks listed below will accept up to
2 #12-#24 solid or stranded wires. Types KA1, KA3, KA31, and KA33 NC contacts are direct opening.
