Rheem SP1082-003 Limit Thermostat
This Rheem SP1082-003 thermostat acts as a limit control for residential water heaters. It uses a single-pole double-throw snap-action switch to manage power to the heating elements. The control range spans 80 to 140 degrees Fahrenheit. It is built for direct replacement in compatible Rheem water heater models.
Suits standard electric water heater repairs
Installers replacing a failed high-limit or surface-mount thermostat in a matching Rheem tank will find the correct switch action and temperature span here. Builders needing a three-pole contactor or a control with a lower minimum setting should look at other part numbers. The fixed 6 inch length and 3.9 inch width also limit fitment to specific bracket layouts.
25 A at 277 V contact rating
The double-throw switch carries 25 amperes at 277 volts or 30 amperes at 120 and 240 volts. This rating determines whether the thermostat can directly switch the element load or must drive a separate contactor. Verify the heater element amperage against these figures before specifying the part.

Questions about this item
How much heat does the SP1082-003 thermostat generate when it runs continuously?
The thermostat is a switch that controls the heating elements; its own heat output is negligible during normal operation.
What existing wiring and voltage supply must I have for this thermostat to function?
It requires a 120/240 V circuit with wiring rated for at least 30 A and a pilot-duty circuit rated for 125 VA at 120/480 V.
Will this thermostat work with the original heating elements in my older Rheem water heater?
Yes, it controls power to standard heating elements up to 3,600 W at 120 V within the 80-140 °F range.
