Key Benefits Enhanced Control Precision: Facilitates accurate high-limit sensing and thermal management during the heating cycle

For immersion applications

Ensure the thermocouple is generating at least 25-30mV under load before replacing the magnet head

Standard 24V Control: Engineered for easy integration with standard thermostat circuits and low-voltage control systems

this switch can be used in other applications requiring a 150/120 setpoint
