3/8" MPT High Limit Switch – 230°F with 68" Lead for Hot Water Pressure Washers

3/8" MPT High Limit Switch – 230°F with 68" Lead for Hot Water Pressure Washers

Protect your hot water pressure washer from excessive temperatures with this 230°F High Limit Switch with 68" Lead. Featuring a 3/8" Male NPT connection, this temperature-activated safety switch is designed to interrupt the burner control circuit when the preset temperature limit is reached.

The extra-long 68-inch lead provides plenty of flexibility for routing the wiring to burner controls on larger machines or installations where the control components are located farther from the heating coil.

• Temperature-activated burner safety control

• Helps protect against excessive water temperatures

• Provides an additional safeguard for the burner and heating coil

• Ideal for commercial and industrial hot water pressure washers

What it does:

The high limit switch monitors temperature within the pressure washer's heating system. If the temperature reaches approximately 230°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 regulates the pressure washer's normal operating temperature. The high limit switch is a safety device that provides an additional cutoff when the system reaches its preset temperature limit.

Why it matters:

A properly functioning high limit switch helps protect against:

• Excessive water temperatures

• Burner overheating

• Heating coil damage

• Damage to hoses, seals, and other components

• Unsafe equipment operation

The combination of a 230°F fixed temperature setting, 3/8" MPT connection, and extra-long 68" lead makes this high limit switch a convenient replacement for compatible commercial hot water pressure washer systems.
