Selector Switch Contact Block

The Dayton 30G320 is a 30 mm contact block designed for industrial control panels and machinery. It provides one normally open and one normally closed contact for momentary selector switch operators. The unit carries a 10 A rating at 600 V AC or DC and meets NEMA A600/Q600 designations. It is suited for electricians and maintenance teams building or repairing starter circuits.

Installation and Compatibility

The block mounts on a 30 mm operator such as the 30G319 selector switch and uses a break-before-make action. Wiring follows standard terminal layout for 1NO/1NC configurations. A common issue is ordering the block without verifying the operator model, as it fits only listed compatible operators. The clear housing aids visual inspection of contact movement during testing.

Contact Rating Decides Fit

The 10 A at 600 V AC/DC rating with NEMA A600/Q600 designation is the single specification that determines whether this block matches the load requirements. Buyers needing higher current capacity or a different voltage class must select another part. The cRUus component recognition and CE marking confirm compliance for panel builds.
