this double-pole limit control provides essential circuit protection for Nordyne air handlers and electric furnaces by breaking two independent electrical paths simultaneously when overheating is detected

The forged brass construction and nickel-plated stem provide the durability needed for closed-loop systems

While it can switch higher voltage loads on the contact side up to its rated capacity

It operates with a 24 VAC coil featuring 90 Ohms DC resistance and a 125 mA nominal current draw

Lennox 27K12 Limit Switch Els PW 17895 this double-pole limit control providesThe Lennox 27K12 Limit Switch is a critical safety component designed for precise thermal regulation within various residential furnace and HVAC systems. Engineering as a normally closed (NC) switch, this automatic reset limit switch is tasked with monitoring heat exchanger temperatures to prevent hazardous overheating conditions. It features a specific 3 inch insertion depth, allowing for accurate probe placement within the supply plenum air stream.
