Ruud RXTB-A10 High Pressure Limit Kit Auto Reset 610 Psig

Product Description

The RUUD RXTB-A10 is an auto-reset high pressure limit kit designed for refrigeration and air conditioning systems where refrigerant-side high-pressure protection is required. The switch opens at 610 psi (plus or minus 10 psi) and resets automatically when pressure drops to 420 psi (plus or minus 15 psi). The sweat-type refrigerant connection terminates at a 90-degree elbow with a 1/4-inch connection size, making it straightforward to integrate into existing refrigerant circuits. Licensed HVAC technicians handling refrigerant-side components will be the primary installers of this kit.

This high pressure limit kit is suited for residential and light commercial HVAC and refrigeration applications where automatic high-pressure cutout protection is needed. It replaces OEM part number 47-103669-04, making it a direct drop-in for systems that originally carried that component. The 18 AWG lead wires measure 54 inches in length, providing adequate reach for most control circuit connections without splicing.

Key Features

• Auto-reset operation — no manual reset required after pressure normalizes
• Opens at 610 psi with a plus or minus 10 psi open-pressure tolerance
• Closes at 420 psi with a plus or minus 15 psi close-pressure tolerance
• Sweat-type refrigerant connection with 90-degree elbow and 1/4-inch connection size
• 18 AWG lead wires at 54 inches in length for flexible wiring routing
• Direct replacement for OEM part number 47-103669-04

Compatibility

Direct replacement for systems originally equipped with OEM part number 47-103669-04. Designed as an OEM-style high pressure limit replacement for RUUD and Rheem refrigerant systems specifying this pressure limit configuration.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the involvement of refrigerant-side components. Recover refrigerant and confirm system pressure is at zero before cutting or sweating any connections. Use appropriate brazing techniques and follow all local mechanical codes when making sweat connections. Verify control circuit wiring connections match the original wiring configuration before restoring power and refrigerant charge.
