Enviro-tec PE-09-6240 Switch

The Enviro-tec PE-09-6240 is a specialized high-limit cutout switch engineered for precise thermal protection in commercial fan coil units and air handling systems. This manual reset limit switch functions as a critical safety component, featuring a fixed 240°F (115°C) trip point to prevent heat exchanger damage or unsafe duct temperatures. Designed for 240V AC operation, this SPST (Single Pole Single Throw) device interrupts the control circuit upon reaching its thermal threshold, requiring a manual intervention to restart the system, which ensures the underlying cause of the overheat condition is addressed by a technician.

The PE-09-6240 is a direct OEM replacement part, frequently utilized in Enviro-tec VAV boxes and blower coil assemblies. Its rugged construction ensures reliable thermal circuit interruption under high-cycling demands. When replacing this switch, confirm the cut-off temperature rating and mounting footprint match the existing heater assembly or plenum housing to maintain UL compliance and system safety integrity.

• Manual Reset Mechanism: Ensures positive lockout until manual inspection, preventing dangerous thermal cycling.
• OEM Compatibility: Specifically designed for Enviro-tec HVAC equipment, ensuring proper fitment and electrical load rating.
• 240F Fixed Setpoint: Provides accurate over-temperature protection for electric heat sections and ducting.
• Durable Construction: Built for high-voltage commercial applications with reliable electrical contact performance.

Common HVACR Technical Questions

Can this switch be used in 120V or 208V circuits?
While rated for 240V, the Enviro-tec PE-09-6240 can typically handle lower voltages as long as the amperage draw does not exceed the manufacturer's maximum contact rating. Always verify the Full Load Amps (FLA) of your specific application.

What causes this high limit switch to trip frequently?
Recurrent tripping is usually a symptom of restricted airflow, such as clogged filters, a failing blower motor, or incorrectly sized ductwork causing excessive static pressure over the heating elements.

Is this switch field-adjustable?
No, the PE-09-6240 features a factory-set, non-adjustable 240-degree trip point to ensure the safety limit remains consistent with the equipment's original engineering specifications.
