Eaton A27CGF45B057 Air Compressor Magnetic Motor Starter for 15hp Compressors on 208-230v/3ph Power

The Eaton A27CGF45B057 is a definite purpose air compressor magnetic motor starter. This is designed for use with air compressors that have a 15hp motor and are running on either 208v/3phase or 230v/3phase power. This will not work with single phase air compressors.

A27CGF45B057 is manufactured by Eaton / Cutler Hammer. This includes a pre-installed contactor, coil and overload. The A27CGF45B057 is specifically used on 15hp air compressors that are running on 208-230v 3 phase power. The overload is adjustable between 40 and 57 amps. Most 15hp compressors on 208-230v/3ph power will fall within this range, however we highly recommend verify the full load amp draw on your compressor motor to ensure this is correct before ordering. 

A27CGF45B057 does not include an on/off switch. You will want to utilize your pressure switch, breaker, or fusible disconnect to turn the compressor on and off.

Featuring components that meet IEC design and UL horsepower ratings and design standards, Eaton mag starters are UL Recognized and use CSA Certified contactors. No internal starter heaters are required, simply wire this into your pressure switch and motor. Three phase motor starters provide overload protection to electric compressor motors. This is similar to a surge protector for your compressor – a motor starter adsorbs the incoming power before it is sent into your electric motor. This helps to prevent costly damage to the windings from over-currents and temperature increases. A magnetic starter is required for all three phase compressors and any single phase application where there is no overload protection for the motor. Eaton A27 starters are pre-wired from the factory and recommended for all single and three phase applications where magnetic starters can be applied.
