Allen-Bradley 836-C63A Pressure Controls Device Style C

Allen-Bradley 836-C63A is a Style C electro-mechanical pressure control switch designed for general industrial use in a NEMA Type 1 enclosure, featuring stainless steel external bellows (Style C) with an actuator that can be supplied in copper alloy or stainless steel Type 316. It operates from a 600 V supply and uses a cable-screw gland for electrical connection, and it supports air, water, and oil service. The unit provides an adjustable operating range of 4 to 150 psi with an adjustable differential of 2.5 psi, and it is rated for line pressures up to 270 psi (occasional surges up to 270 psi). The standard control configuration is a 2-circuit SPST NC contact block with non-inductive ratings of 5 A at 240 V AC and 3 A at 600 V AC, plus control-circuit ratings (AC-125 VA, 24–600 V DC-57.5 VA; note that at 115–230 V the minimum differential roughly doubles). Its compact dimensions are 65.1 mm wide, 62.6 mm deep, and 185.8 mm high, with an approximate shipping weight of 2 lb.
