Robertshaw 5600-411 Thermostat

As a field technician, you need a dependable Robertshaw 5600-411 when servicing residential or commercial electric water heaters. This SPST lower water heater thermostat is engineered specifically for bottom-element control, operating within a precise 120°F to 160°F temperature range. Designed for high-duty cycles, it features snap-action operation to prevent arcing and ensure a clean electrical break, maintaining a tight 7°F to 17°F differential. The 5600-411 thermostat is a direct replacement for Robertshaw EWT-1 and Camco 011, featuring a 3.75-inch compact housing that mounts securely against the tank surface for accurate thermal conduction. With an electrical rating of 30 Amps at 120-250V AC, this electric water heater control handles heavy-wattage loads without premature failure. Whether you are performing a water heater thermostat replacement or troubleshooting recovery issues, this OEM-spec part provides the high-limit safety and automatic cycling necessary to stabilize tank temperatures and prevent overheating.

• Universal Compatibility: Serves as a direct replacement for EWT1 and various lower thermostat cross-references including Rheem, Bradford White, and Camco.
• Industrial-Grade Rating: Rated for up to 30 Amps at 250VAC, making it suitable for high-demand commercial water heating systems.
• Precision Control: Fixed 7° to 17°F differential ensures consistent cycling to extend element life and maintain user comfort.
• Simplified Installation: Features standard screw terminals and a compact mounting bracket for fast replacement in tight access panels.
• Built-In Safety: Integrated automatic cycling technology provides reliable thermal sensing directly against the heater wall.

Is the Robertshaw 5600-411 compatible with upper heating elements?
No, this is a lower thermostat (SPST) specifically designed for the bottom element. For the upper position, a 5600-311 (SPDT with high-limit reset) is typically required.

How do I know if my lower thermostat has failed?
A failed Robertshaw 5600-411 often results in "lukewarm" water once the top of the tank is depleted or a complete loss of recovery efficiency. Always check for continuity across terminals 1 and 2 when the tank is cold.

What is the maximum wattage this control can handle?
The unit is rated for 7200W at 240V AC and 3600W at 120V AC, covering the vast majority of standard dual-element water heaters.
