Raypak 013474F Auto Reset High Limit Switch 200°F

The Raypak 013474F is an automatic reset high limit thermostat switch designed to provide critical overheat protection for Raypak boilers and water heaters. This safety component trips at 200°F, making it suitable for hydronic heating applications and commercial water heating systems that operate at higher temperatures than standard pool and spa heaters.

Key Features:

• 200°F temperature cutout threshold for high-temperature applications
• Automatic reset functionality - switch automatically resets when temperature returns to safe levels
• Surface-mount design for clean, professional installation
• Genuine Raypak OEM replacement part ensures proper fit and reliable operation
• Critical safety device prevents equipment damage and potential hazards from overheating

This high limit switch is commonly used in Raypak's Delta Limited series boilers and commercial hydronic heating systems where output temperatures can reach 200°F for water heaters and up to 230°F for hydronic boilers. The auto-reset feature eliminates the need for manual intervention once the system cools to safe operating temperatures, reducing downtime and service calls.

When the switch detects temperatures exceeding 200°F in the inlet/outlet header or heat exchanger area, it immediately opens the circuit to shut down the heating system. This prevents damage to heat exchangers, headers, and other critical components while protecting against unsafe operating conditions.
