Ashcroft B464B Pressure Switch

Ashcroft B464B pressure switch is an industrial device from the Ashcroft B-Series family; it is specified for a 30 psi pressure setting and a 15 A electrical rating at up to 480 VAC, enabling it to switch moderate-to-high current loads in hydraulic or pneumatic systems while delivering reliable actuation at a fixed threshold for sequence control, safety interlocks, or pump and compressor applications. This specific B464B is listed as discontinued by Ashcroft; when replacing it, technicians typically look to current B-Series offerings that match the same electrical rating and pressure setting to maintain compatibility with existing wiring, enclosure fit, and actuator interfaces. Within the broader B-Series line, Ashcroft provides a variety of enclosure styles and diaphragm materials to suit different media and ambient conditions, allowing the same basic pressure-switch function to operate in environments ranging from clean process facilities to harsher industrial plants.
