Rheem 333F Fuse Link Specifications
The Rheem 44-20037-03 is a fuse link rated at 333 degrees Fahrenheit with a 15-ampere capacity. It operates across 24, 120, and 230-volt systems for universal HVAC applications. This new component serves as a thermal safety device for air conditioning and refrigeration equipment.
Thermal Trip Point and Voltage Limits
The device interrupts the circuit only when temperatures reach the fixed 333F threshold. It cannot be adjusted or reset after activation. The multi-voltage rating covers common control circuits but does not extend to higher industrial line voltages beyond 230 volts.
Replaces Blown Thermal Fuses
This part replaces a fuse link that has already opened due to an over-temperature event. The upgrade is worth it when the original Rheem component fails and the system wiring and controls remain intact. It is not for buyers who need a resettable breaker or a different temperature rating.
