1/2" MPT High Limit Switch – 330°F for Hot Water Pressure Washers

1/2" MPT High Limit Switch – 330°F for Hot Water Pressure Washers

Protect high-temperature hot water pressure washer systems with this 330°F High Limit Switch. Featuring a 1/2" Male NPT connection, this temperature-activated safety switch is designed to interrupt the burner control circuit when the preset temperature limit is reached.

With its high 330°F temperature setting, this switch is intended for compatible high-temperature or steam-capable pressure washer systems where a standard lower-temperature limit switch is not suitable.

Specifications:

• Type: High Limit Temperature Switch

• Temperature Setting: 330°F

• Connection: 1/2" Male NPT

• Application: High-Temperature Pressure Washer Burner Safety Control

Applications:

• Hot water pressure washers

• High-temperature pressure washer systems

• Steam-capable cleaning equipment

• Oil-fired burner systems

• Commercial and industrial cleaning equipment

• Replacement and custom-built pressure washer systems

Features:

• Fixed 330°F temperature setting

• 1/2" Male NPT connection

• Temperature-activated burner safety control

• Helps protect the heating system from excessive temperatures

• Provides an additional safeguard for the burner and heating coil

• Designed for demanding high-temperature cleaning equipment

What it does:

The high limit switch monitors temperature within the heating system. When the temperature reaches approximately 330°F, the switch changes electrical state to interrupt the burner control circuit, preventing the burner from continuing to add heat.

High Limit Switch vs. Thermostat:

An adjustable thermostat controls the machine's normal operating temperature. The high limit switch serves as a safety device, providing an additional temperature cutoff if the system reaches its preset limit.

Why it matters:

A properly functioning high limit switch helps protect against:

• Excessive operating temperatures

• Burner overheating

• Heating coil damage

• Damage to temperature-sensitive components

• Unsafe equipment operation

Important:

330°F is an extremely high temperature. This switch should only be used on equipment specifically designed for this temperature range. Verify that the pressure washer, heating coil, hose, gun, fittings, seals, valves, and other components are properly rated for the intended operating temperature and pressure.

The 1/2" MPT 330°F High Limit Switch is an important safety component for compatible high-temperature commercial and industrial pressure washer systems.
