Dayton 30G076 22 mm 1NC contact block industrial power supply

Contact block for operator stations

The Dayton 30G076 is a 22 mm mounting-base contact block with a single normally closed circuit, designed for industrial control panels and operator interfaces. It pairs with chrome or plastic operators in momentary-action applications such as emergency-stop or interlock circuits. The red housing provides quick visual identification in dense panel layouts. Screw-clamp terminals accept standard wiring for secure connections.

Rated currents for control-circuit duty

The block carries 1.2 A at 600 V AC, 3 A at 240 V AC and 6 A at 120 V AC, matching NEMA A600/Q600 designations for pilot-duty loads. CE, CSA, IEC and UL listings confirm compliance with international safety standards for industrial machinery. No internal cooling or external power supply is required; the device operates passively within the enclosure. Heat rise stays low during normal contactor or relay driving.

Continuous operation within rated limits

Under sustained load the contacts remain closed without degradation as long as current stays at or below the stated ratings for the applied voltage. The momentary action returns the circuit to open when the operator is released, preventing unintended hold-in conditions. Builders who need a normally open contact or multiple poles must select a different block, as this unit provides only one NC circuit.
