This Harmony XAC, double contact block uses screw-clamp terminals and has 1 x NO + 1 changeover contact SPDT single pole double throw. This contact block allows fast and easy replacement and configuration of your push buttons and selector switches. It is easily installed and replaced on XACM and XACB pendant control stations and connects to control circuits with simple screw-clamp connections. It protects operators from unexpected contact with live circuits thanks to its IP20 protection index. It has clear labelling of the contact wiring and terminals names on the side of the block. Vibration resistant screw clamp connection terminals ensure high vibration resistance making product suitable installation on high impact machine.
