Ashcroft T424T10030BX260 Temperature Switch 150-260F

Product Description

The ASHCROFT T424T10030BX260 is a watertight single setpoint temperature switch designed for industrial and commercial process control applications. It uses a capillary stem type with a 10-foot capillary line, allowing remote sensing of temperature at a distance from the switch body. The operating temperature range spans 150 to 260 degrees F, making it suitable for monitoring hot fluid systems, HVAC hydronic circuits, and process piping. Licensed HVAC technicians, pipefitters, and industrial maintenance technicians are the primary installers. The watertight enclosure protects internal contacts from moisture ingress in demanding field environments.

This temperature switch is applicable in residential and commercial hydronic systems, industrial process lines, and equipment protection circuits where a single fixed-setpoint trip is required. The capillary design allows the sensing bulb to be placed directly in the medium being monitored while the switch body is mounted in a dry, accessible location. Typical installations include boiler high-limit control, heat exchanger protection, and hot water process monitoring.

Key Features

• Watertight enclosure for use in wet or outdoor installation environments
• Single setpoint design provides a discrete switching action at the selected trip temperature
• Temperature range of 150 to 260 degrees F covers common hot water and process fluid applications
• 10-foot capillary allows remote bulb placement away from the switch body
• Capillary stem type enables flexible routing in tight or complex equipment layouts

Compatibility

Designed as an OEM-style or replacement single setpoint capillary temperature switch for commercial and industrial control systems requiring a watertight enclosure and a 150 to 260 degrees F operating range.

Installation Notes

Installation should be performed by a licensed HVAC technician, pipefitter, or qualified industrial electrician in accordance with applicable NEC and local electrical codes. De-energize all circuits and shut off the process fluid supply before removing or installing the switch. Avoid sharp bends or kinks in the capillary line during routing, as damage to the capillary will affect switch accuracy. Ensure the sensing bulb is fully immersed in the monitored medium and that all conduit entries are sealed to maintain the watertight rating.
