The enclosure that protects this industrial pressure switch is a Type 1, 4, and 13 rated enclosure that can protect the switch against most common industrial pollutants. The bellows that are installed in the 836T-T254JX40 pressure control switch are made from copper alloy, and they are suitable for applications that involve exposure to water, dust, air, and any vapors, gasses, or chemicals that are not corrosive to copper alloy. The 836T-T254JX40 pressure control switch does not come with any modification options and its maximum line pressure rating is 600 PSI.

The Allen-Bradley 836T-T254JX40 pressure control switch from the 836 pressure controls series is a T-style pressure control switch, which means that it has independently adjustable operating and differential pressure ranges, and just 1 set of copper alloy bellows for operation. Its factory default settings include the maximum operating pressure setting and the minimum differential pressure setting. The 836T-T254JX40 pressure control switch is suitable for most traditional machine tool systems and applications. It meets the UL, CSA, and CE standards. The 2 adjustable pressure ranges that the 836T-T254JX40 pressure control switch handles can be adjusted with screws. The screw for adjusting the operating pressure range is located on the top of the switch and it is protected by a locking nut. The screw for adjusting the differential pressure range is located on the front of the switch.
