Heil Quaker ICP 1171160 Contactor

The Heil Quaker ICP 1171160 Contactor is a heavy-duty 2-pole 20A 24V contactor engineered for precise electrical load management in residential and light commercial HVAC systems. As a critical inductive switching component, this OEM HVAC contactor facilitates the seamless operation of compressors and condenser fan motors by opening and closing energized circuits via a 24V AC coil. Designed to withstand the rigors of high-cycle frequency, the ICP 1171160 features durable silver-cadmium oxide contacts that resist pitting and welding, ensuring superior conductivity and thermal stability. This definite purpose contactor is a direct drop-in replacement for specified International Comfort Products (ICP) units, providing the exact mounting footprint and terminal orientation required for professional field service. By maintaining stable contact pressure, it minimizes voltage drops and prevents premature component failure caused by electrical arcing or heat fatigue in demanding environments.

• 2-Pole Configuration: Provides reliable switching for both legs of a single-phase power supply, enhancing system safety.
• Optimized 24V Coil: Designed for low-voltage control circuits, ensuring compatibility with standard HVAC transformers and thermostats.
• 20 Amp FLA Rating: Robustly rated for Full Load Amps to handle the high-inrush current of start-up cycles.
• Compact DP Design: Fits standard electrical enclosures, simplifying the replacement process for service technicians.
• High-Grade Construction: Built to endure extreme temperature fluctuations within condensing units for long-term service life.

What are the signs that a contactor needs replacement?
Technicians should look for pitted or "chattered" contact points, a humming or buzzing 24V coil, or a failure of the outdoor unit to engage despite receiving a call for cooling from the thermostat.

Can I use a 2-pole contactor to replace a 1-pole contactor?
A 2-pole contactor like the 1171160 is often preferred as it breaks both sides of the line, providing an extra layer of safety by ensuring no power reaches the load when the contactor is de-energized.

Is this part compatible with 50Hz and 60Hz systems?
Yes, the coil on this ICP 1171160 is rated for 50/60Hz, making it suitable for a wide range of regional power standards in compatible equipment.
