International Environmental 70006007 Limit Switch

The International Environmental 70006007 Limit Switch is a critical OEM replacement part designed for precision temperature monitoring in fan coil units and air handling systems. Engineered as an L200-60F high limit switch, this safety device features a fixed 200?F opening setpoint with a 60?F differential, ensuring the HVAC system remains within safe thermal operating parameters. When internal temperatures rise to the limit, the switch breaks the electrical circuit to prevent equipment damage, subsequently auto-resetting once the environment cools to 140?F.

Built for the rigors of commercial and residential heating and cooling applications, this bimetal disc limit control offers an automatic reset function that eliminates the need for manual intervention after a temporary thermal excursion. For technicians performing furnace repair or airflow diagnostics, the 70006007 provides reliable overheating protection. Its compact design and standard mounting footprint allow for seamless integration into IEC equipment, maintaining energy-efficient HVAC performance and protecting vital system components from high-heat stress.

• Snap-Action Reliability: Features a high-response bimetal disc for accurate switching at the 200?F threshold.
• Automatic Reset Logic: Resumes normal operation automatically at 140?F, reducing unnecessary service calls for simple thermal trips.
• Equipment Versatility: Direct OEM fit for a wide range of International Environmental Corporation (IEC) fan coils and air handlers.
• Durable Construction: Engineered to withstand high-cycle thermal stress without drifting from setpoint specifications.

How do I know if my high limit switch is failing?
Common symptoms include the system short-cycling, the blower motor running continuously while the heat source is disabled, or the furnace failing to initiate the heating cycle due to an open circuit. Always check for airflow restrictions like clogged filters before replacing the switch.

What does the L200-60F designation mean for this part?
The "L" stands for Limit, "200" is the temperature in degrees Fahrenheit at which the switch opens (breaks the circuit), and "60F" is the differential, meaning it will close again at 140?F (200 - 60).

Can this switch be used in other HVAC brands?
While functionally similar to other limit controls, the 70006007 is specifically designed for International Environmental equipment. Always verify mounting orientation and terminal sizing to ensure a proper match for your specific application.
