The Allen-Bradley/Rockwell Automation replacement enclosure with  the catalog number 836-N58 is used for pressure switches from the 836-C product line. This Style A enclosure is labeled as a Type 1 enclosure and it can be purchased separately from the pressure switch it protects just like other replacement parts that are available for this series. The manufacturer provides other replacement parts for Style C devices like replacement contact blocks and replacement pilot lights. The 836-N58 replacement enclosure is used for several different Allen-Bradley 836 Pressure Controls devices. However, the 836-N58 enclosure is only intended for certain types of pressure controls from this series, not every model. The 836 pressure controls are made of contact blocks, differential cams, trip indicating scales, mounting brackets, operating pressure and differential adjustment screws, external bellows, clear contact inspection covers, finger-safe contact block shields, and self-lifting pressure plate terminals.

The Allen-Bradley/Rockwell Automation 836 series 836-N58 enclosure is used for 836 Pressure Controls that are used for general industrial applications and that are built for use with industrial pneumatic and hydraulic systems. These controls are available in Type 1, 4, and 13, 4X, 7 & 9, and 4 & 13 rated enclosures and they support multiple mounting options. These pressure controls are used for applications like compressed air monitor systems, liquid level control, vacuum transfer systems, high-pressure alert, low-pressure alert, and air compressor applications. The typical operating temperature range of these devices is -30 to 66 degrees Celsius (-22 to 150 degrees Fahrenheit) while their storage temperature range is -30 to 93 degrees Celsius (-22 to 200 degrees Fahrenheit). These pressure controls can have an internal or external bellows made from copper alloy or stainless steel.
