Emergency Stop Button 22 mm

The Dayton 30G250 is a 22 mm maintained-action emergency stop push button designed for industrial control panels. It features a red 40 mm mushroom head made from nitrile rubber with a plastic bezel. The unit carries a 1NO/1NC contact form rated at 10A at 600V AC and meets NEMA A600/Q600 designations. It is UL listed and compliant with CE, CSA and IEC standards.

NEMA 4X Environmental Rating

The button achieves NEMA ratings 1, 2, 3, 4, 4X, 12 and 13 for protection against dust, water and corrosion. Pressure-plate terminals allow secure wiring without specialised tooling. The plastic construction resists common industrial contaminants while the maintained action keeps the circuit open until the operator is deliberately reset. No legend plate is included with the unit.

10A 600V AC Contact Capacity

The single-operator switch handles control-circuit loads up to 10 amperes at 600 volts AC within the A600/Q600 rating envelope. It suits standard emergency-stop functions on machinery and panels where a maintained red mushroom head is required. Applications demanding higher current ratings, multiple operators or illuminated heads fall outside this device's specification.

Questions about this item

How often should the nitrile rubber mushroom head on this 22 mm emergency stop button be inspected or replaced?

Inspect the 40 mm nitrile rubber mushroom head regularly for cracks or wear; replace it immediately if the maintained action no longer latches or the red colour has faded.

What is the first limit reached when the button is held in the latched position for long periods?

The 10 A at 600 V AC contact rating and NEMA A600/Q600 designation set the electrical limit; sustained current above 10 A will exceed the switch capacity.

How much heat does the pressure-plate terminal block generate when the switch carries 10 A continuously?

At the rated 10 A the contacts and pressure-plate terminals will warm up, but the plastic bezel and NEMA 4X rating are designed to dissipate that heat without exceeding safe surface temperatures.
