Raypak 008520F 240F CO M/R Limit Switch

Description

Raypak 008520F 240°F Manual Reset Limit Switch Overview

The Raypak 008520F is a 240°F cut-out (CO) manual reset (M/R) limit switch engineered as a genuine OEM safety component for Raypak heating and hydronic systems. Designed to protect equipment from dangerous overtemperature conditions, this limit switch interrupts the control circuit when the sensed temperature reaches 240°F, requiring a manual reset before the system can resume operation — ensuring a technician inspects and resolves the root cause before restart.

Key Features

• 240°F cut-out temperature rating for precise high-temperature protection
• Manual reset (M/R) operation requires deliberate technician intervention after a trip event
• Cut-out (CO) design interrupts the control circuit to shut down the appliance on overtemperature
• Genuine Raypak OEM replacement part for reliable, like-for-like performance
• Direct replacement for compatible Raypak boilers and water heaters
• Helps protect heat exchangers, burners, and system components from thermal damage

Application

The 008520F limit switch is a critical safety device used in Raypak boilers and hydronic heating equipment. When the system temperature exceeds the 240°F threshold, the switch opens the control circuit and locks out the burner. The manual reset feature prevents automatic restart, prompting a qualified HVAC/R technician to diagnose and correct the underlying issue before returning the system to service.
