Modine High Limit Switch Boiler Safety Controls & Aquastats

The Modine high limit switch is a heater safety control, also called a limit switch or overheat safety switch. It guards against overheating in heating equipment. It monitors temperature inside the unit. If temperature goes above the preset limit, it interrupts the electrical circuit. This helps prevent damage to the heater and reduces the risk of fire.

Key Features:

• Temperature-actuated safety switch that opens the circuit when the preset limit is exceeded
• Designed as a replacement safety control for Modine heating equipment
• Helps protect heating components from overheating damage
• Available in multiple temperature-limit versions under the Modine line

This line suits maintenance and repair of Modine heating systems. Each part number in the line has its own temperature-limit rating, shown in its listing.
