Lennox 17K71 Circuit Breaker
The Lennox 17K71 Circuit Breaker (Model 17K7101) is a high-performance 2-pole 45A common-trip breaker designed for critical circuit protection in residential and commercial HVACR equipment. This 120/240V overcurrent protection device is engineered to safeguard compressors and fan motors from electrical faults, effectively preventing damage caused by short circuits or sustained thermal overloads. As a veteran-grade HVAC replacement part, it ensures the electrical integrity of Lennox units, providing reliable interruption of power when fault conditions are detected. Its robust construction is rated for the high in-rush currents typical of HVAC startup cycles, making it a staple for field technicians performing proactive maintenance or emergency system repairs. This Lennox 17K7101 breaker features a standard plug-in or bolt-on mounting profile (depending on the panel type) and represents a vital component in maintaining system uptime and operational safety in demanding environments.
Key Benefits:- Provides 45-amp circuit protection specifically calibrated for HVAC motor loads and air handling units.
- Features a 2-pole common trip mechanism to ensure simultaneous disconnection of both legs of the circuit during a fault.
- Minimizes downtime by offering a reliable overload protection solution that withstands harsh mechanical room conditions.
- Direct OEM replacement for Lennox Part Number 17K71, ensuring perfect fitment and adherence to original equipment specs.
What are the symptoms of a failing Lennox 17K71 circuit breaker?
Technicians often see breakers that won't reset, exhibit carbon tracking on the bus bar connection, or trip immediately upon compressor engagement due to internal fatigue.
Is this 45-amp breaker compatible with other brands?
While this part is specifically cataloged as Lennox 17K71, it is often a Square D style component. Always verify the panel bus bar type (Homeline vs. QO) and full load amperage of the equipment before installation.
Can I use a 50A breaker if this 45A unit keeps tripping?
No. You must adhere to the MOP (Maximum Overcurrent Protection) listed on the equipment nameplate to ensure safe operation and prevent electrical fires.
