Ashcroft PTDN4GG15A7030 XBX Temperature Switch

Ashcroft PTDN4GG15A7030 XBX Temperature Switch is a P‑Series industrial temperature switch designed for high‑temperature limit control with a 235–375°F (approximately 113–190°C) setpoint range and a 480 VAC electrical rating. It supports direct mounting via ½" NPT male process connections or remote mounting through the XBX ½" NPT union option, with electrical termination provided by ¾" NPT female conduit connections. Wetted materials are 316 stainless steel, and the unit provides two SPDT contacts that can be configured to function as DPDT in the appropriate wiring arrangements. The PTDN model accommodates single or dual setpoints and offers configurable deadband options, including field‑adjustable or factory‑setpoints depending on configuration, enabling tailored response for a given process. This model is catalogued as discontinued by Ashcroft distributors, reflecting movement toward newer temperature‑switch families, yet it remains representative of Ashcroft’s robust, industrial‑grade design. Typical uses include refinery and chemical plant controls, power generation equipment, and water and wastewater treatment processes where a reliable high‑limit or alarm switch is required to monitor temperature and trigger appropriate shutdowns or alarms.
