Copeland 912-3075-01 Contactor
The Copeland 912-3075-01 is a heavy-duty definite purpose contactor engineered for high-demand HVACR and industrial applications. Built for switching and motor control in residential and commercial cooling systems, this 75 amp contactor features a 3-pole configuration, allowing it to handle three-phase power loads up to 600V. The 120v coil ensures reliable actuation, providing a standard control voltage interface for most thermostat and controller circuits. As a direct Copeland replacement part, this model is designed for seamless physical and electrical compatibility with existing equipment housings, reducing downtime during field service. The silver-cadmium oxide contacts are optimized for durability under high inductive loads, preventing premature pitting or welding. For contractors managing compressor motor control, the 912-3075-01 offers the standard footprint and terminal orientation required for professional repairs and refurbishments.
Key Benefits- High Capacity Output: Rated for 75 amps, making it suitable for larger condensing units and refrigeration compressors.
- Robust 3-Pole Design: Provides simultaneous switching for all three phases of power, ensuring balanced motor operation.
- Standard 120V Coil: Simplifies integration into existing 120-volt control circuits without the need for additional transformers.
- Definite Purpose Reliability: Built specifically to handle the high inrush currents typical of HVAC motor starting.
- Direct Fit: Maintains the exact mounting specifications and wiring layout of the original Copeland 912-3075-01.
Is the 912-3075-01 compatible with single-phase systems?
While this is a 3-pole contactor designed for three-phase equipment, it can technically be used in single-phase applications by utilizing only two of the poles; however, verify that the 75A rating matches your load requirements.
Does this unit include auxiliary contacts?
Standard configurations of the Copeland 912-3075-01 often support auxiliary snap-on blocks, but the base unit is primarily designed for the main 3-pole power circuit.
What causes this contactor to hum or chatter?
In most field scenarios, chattering is caused by low voltage to the 120v coil or debris between the armature and magnet. Ensure clean connections and a stable power supply to resolve noise issues.
