Industrial 100-135 PSI 26 Amp Pressure Switch

Industrial 100-135 PSI 26 Amp Pressure Switch is an industrial-control device that automatically starts and stops air compressors by monitoring receiver tank pressure. This non-OEM comparable unit is designed for applications requiring a 100 PSI cut-in and 135 PSI cut-out with a 26 Amp electrical rating, making it suitable for single-stage reciprocating compressors, shop compressors, and larger industrial air systems. Key specifications include a 100 PSI cut-in, 135 PSI cut-out, 35 PSI differential, maximum 26 Amp current, voltage rating of 120/240 VAC (application dependent), and single-phase operation. The switch features a 1/4 in. NPT manifold connection and is commonly offered with a manual ON/OFF lever and an unloader valve (model dependent); enclosure is NEMA Type 1 (application dependent). It serves as a reliable replacement in preventive maintenance projects to restore proper pressure cycling and protect equipment from over-pressurization. Common replacements include Ingersoll Rand 23474661, Condor MDR 11, and Square D 9013FHG42J59M1X. Typical targets for replacement installations include Ingersoll Rand SS3L3, SS4L5, SS5L5, and similar reciprocating compressors, as well as other compatible industrial and commercial air systems.
