Allen-Bradley 836T-T302J Pressure Switch

The Allen-Bradley 836T-T302J is an electro‑mechanical pressure switch in the 836T Bulletin family, a traditional machine‑tool, T‑style pressure control designed for enclosure Type 1, 4 and 13 industrial use with a rating up to 3000 psi. It uses a SPDT two‑circuit contact block and offers a plug‑in electrical connection; pressure connections are available as 3/8 in NPTF female pipe thread or SAE 7/16‑20 UNF‑2B thread with an O‑ring boss seal for flexible installation. Electrical ratings include a break current of 720 VA at 72–120 VAC and a make current of 7200 VA at 120–600 VAC, with IEC AC‑15, DC‑13 and NEMA A600 utilization categories, and its standard trip/reset settings are factory‑set for the maximum operating range and minimum differential. Operating temperature is −22 °F, and the unit is configured with a 2‑circuit SPDT contact block to control the connected process; the model is commonly listed with an operating range of 200–3000 psi and a differential of 175–400 psi for this variant.
