Lennox 17K70 Breaker
As an HVAC pro, you know a tripped breaker isn't just a nuisance—it’s a diagnostic signal. The Lennox 17K70 (also identified as 17K7001) is a 2-pole 30 Amp circuit breaker engineered specifically for high-demand 120/240V AC HVACR applications. Built to handle the rigorous inrush currents of compressor startups, this Common Trip breaker ensures that if one leg faults, both poles disconnect simultaneously to prevent single-phasing and potential motor burnout. This UL 489 certified component is the standard overcurrent protection for various Lennox CBX32M series air handlers and residential split systems.
When replacing a worn-out unit, HVAC circuit breaker compatibility is critical. The 17K70 features a plug-in installation design for rapid field replacement in compatible load centers and Lennox-specific control boxes. Its compact footprint is ideal for tight service panels, and the thermal-magnetic trip curve is precisely calibrated for overload and short-circuit protection in light commercial and residential environments. Use this OEM Lennox 17K70 breaker to restore system reliability and adhere to NEC/CEC local codes during your next service call.
Key Benefits:
- Simultaneous Disconnection: The common trip mechanism prevents single-phasing, safeguarding the blower motor and compressor from unbalanced voltage.
- High-Amperage Reliability: Rated for a 30A current rating to support heavy-duty HVAC heating and cooling cycles without nuisance tripping.
- Industrial-Grade Construction: Designed for 120/240V split-phase systems, providing stable electrical protection in harsh mechanical environments.
- Technical Compliance: Meets UL 489 standards, ensuring the part satisfies strict safety regulations for commercial and residential circuit protection.
Common Questions:
Is the Lennox 17K70 compatible with other breaker panels?
While designed primarily for Lennox air handlers and specific load centers, it follows standard sizing for 2-pole plug-in breakers. Always verify the bus bar alignment and panel labeling for 30 Amp 2-pole breakers before installation.
What causes this breaker to trip on a Lennox air handler?
Common triggers include a shorted electric heat strip, a grounded compressor, or a failing blower motor drawing more than the 30A rated amperage. Always check the Minimum Circuit Ampacity (MCA) on the unit nameplate.
Can I use a 30 Amp breaker for a 25 Amp application?
No. You must match the maximum overcurrent protection (MOP) specified on the HVAC equipment. Using a higher amperage breaker than specified poses a fire risk and can lead to catastrophic component failure.
