Barksdale T2H-H251 Temperature Switch 50-250F Capillary

Product Description

The BARKSDALE T2H-H251 is a remote mount temperature switch designed for industrial and commercial control applications requiring accurate temperature-based switching across a wide range. Rated from 50 to 250 degrees F, this unit uses a capillary stem type to sense temperature at a point remote from the switch body. The contact configuration is Dual Set Point SPDT, allowing two independent switching events within a single device. Licensed HVAC technicians, industrial maintenance techs, and controls specialists install this type of switch for process control, equipment protection, and HVAC system monitoring.

This temperature switch is suited for applications where the sensing point must be located away from the switching enclosure, such as duct-mounted sensing, pipe-sensing in hydronic systems, or equipment monitoring in commercial HVAC and light industrial environments. The copper capillary construction supports reliable thermal response in these typical installations. The Dual Set Point SPDT contact form enables high and low limit control from a single device, reducing component count in panel or equipment builds.

Compatibility

Designed as an OEM-style replacement or direct-install remote mount temperature switch for commercial HVAC, process control, and light industrial control panel applications requiring capillary-type temperature sensing.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified controls specialist. De-energize all associated control circuits before mounting or wiring this switch. Capillary-type temperature switches require careful routing of the capillary tube to avoid kinking or sharp bends that can compromise sensing accuracy. Wiring should comply with applicable NEC requirements for control circuit installations.
