Supco L340 Limit Switch
The Supco L340 Limit Switch is a professional-grade snap disc temperature limit control engineered for high-demand HVAC and heating applications. This open-on-rise limit switch serves as a critical safety component, featuring a precision-calibrated 340°F cut-out and a 300°F cut-in, providing a consistent 40°F differential. Built with a 3/4-inch bimetal disc and rugged welded construction, this auto reset furnace limit ensures electrical circuit integrity for sensitive heating equipment, furnaces, and domestic dryers. It is a direct 626194R replacement and also replaces part numbers 60T11-610081 and LS2-340.
Designed for easy integration, the L340 features 1/4-inch quick-disconnect terminals and is rated for loads up to 25 Amps at 240VAC. For optimal HVAC temperature sensing, this unit should be surface-mounted directly onto heat exchangers or ducts. Its automatic reset functionality eliminates the need for manual intervention once temperatures drop below the 300°F reset threshold, making it a reliable choice for maintaining safe operating conditions in commercial and residential thermostat snap disc applications. This SPST limit switch is UL and CSA certified, ensuring it meets rigorous industry standards for thermal protection.
Key Benefits:- Fixed Thermal Calibration: Precise 340°F trip and 300°F reset points for reliable over-temperature protection.
- Automatic Reset Logic: Bimetal snap disc automatically restores the circuit once safe operating temperatures are reached.
- Universal Compatibility: Direct replacement for Nordyne 626194R and various 60T series controls.
- High Electrical Rating: Capable of handling up to 25A at 240VAC with 1/4" quick-disconnect terminals.
- Durable Construction: Welded components and 3/4" disc design for long-term stability in harsh HVAC environments.
Does this switch require a manual reset?
No, the L340 is an automatic reset control. It opens at 340°F and will automatically close the circuit once the sensed temperature cools back down to 300°F.
What are the electrical load limits for this part?
This limit control is rated for 10A FLA at 120VAC, 5A FLA at 240VAC, and can handle resistive loads (RLA) up to 25A at 240VAC.
Where is this limit switch typically mounted?
It is standard practice to mount the L340 directly on the heat exchanger or within the heater ductwork to ensure immediate and accurate surface temperature sensing.
