Part number 836-C7A is a style C pressure control switch that is manufactured by Allen-Bradley. This switch belongs to the Bulletin 836 product line and has external bellows made of copper alloy material. It is a pressure controller switch of the electromechanical mechanism providing Type 1 industrial enclosure protection in industrial applications. This pressure controller has a closed reset contact block consisting of a single pole and a double throw, snap-like action. This controller has found its use in various industrial pressure systems and other applications such as low-pressure alerts, control of liquid level, air compressors, high-pressure alerts, and compressed air monitor systems. This controller switch maintains pressure by opening its contact when there is a rise in pressure. The apparent power ratings for this Allen-Bradley switch are 125 VA for 24 to 600 VAC and 57.5 VA for 115-230 VDC operating at a frequency of 50 or 60 Hz. The 836-C7A pressure controller device comes with default factory settings that are maintained at maximum operating range and minimum differential psi. The adjustable operating range for this device is 4 to 150 psi. The 836-C7A has an adjustable differential range of 2 to 25 psi with a maximum line pressure of 300 psi, and can withstand an occasional surge pressure of 375 psi. The operational temperature for this controller ranges from -30 to 66 degrees Celsius (-22 to 151 degrees Fahrenheit), while the storage temperature is rated from -30 to 93 degrees Celsius (-22 to 200 degrees Fahrenheit). During its installation, it is fitted with a ¼ inch N.F.T.P female connection. The amperage is rated at 5 amperes for 240 volts and 3 amperes for 600 volts. Pilot light indicators, specialty contacts, and quick connection mechanisms are the accessories supported by this Allen-Bradley 836-C7A pressure control device.
