Description
The Williams Comfort Products P323379 is a 330°F manual reset limit switch designed to protect heating equipment from dangerous overtemperature conditions. When the sensed temperature reaches the 330°F cutout setpoint, the switch opens the circuit (CO — Contacts Open) and locks out the system until a technician manually resets it. This manual reset action ensures that the root cause of the overtemperature event is identified and corrected before the appliance is returned to service, making it an essential safety component for residential and light-commercial heating applications.
