Product Details

The Firstco E146 is a precision-engineered L145-40F limit switch designed for HVAC heating systems. This critical safety component monitors temperature within furnaces and air handlers to prevent overheating and potential equipment damage.

Key Features:

  • Opens at 145°F, automatically resets at 105°F for reliable over-temperature protection
  • Auto-reset design for continuous operation without manual intervention
  • Stainless steel construction ensures durability and corrosion resistance
  • 1/2" NPT mounting thread for secure installation
  • Temperature differential of 40°F nominal provides precise control
  • Compatible with 120/230 VAC systems

This limit switch serves as a vital safety control by interrupting the electrical circuit when temperatures exceed safe operating limits, protecting the system from damage and ensuring safe operation. The automatic reset function allows the system to resume normal operation once temperatures return to safe levels.

Best service

Wonderful customer service and prices. Wish could ship faster. Ordered Friday morning but won’t get to shipping until Monday. Middle of painting my boat and this delay will make me add an additional coat.

All good

Super easy ordering.

Only complaint I have is the fact that the item was at my house before there server ever showed it had shipped. And I had the item for over 4 days b4 I ever received tracking information. But the order was at my door 3 days after I ordered it.

Great experience

Great price! Free shipping!
