12HGA11A51G GENERAL ELECTRIC Relay

Review GENERAL ELECTRIC Auxiliary Relay New

The General Electric 12HGA11A51G is a versatile and reliable AC contactor and coil assembly, designed for use in various industrial and commercial applications. This GE relay is specifically engineered as a 120V AC, single-phase, normally open (NO) and form C contactor, with a 5 ampere contact rating.

The contactor's body is constructed from a robust and corrosion-resistant cast aluminum material, ensuring durability and longevity even in demanding environments. The silver-gray powder coating finish not only enhances the unit's appearance but also provides an additional layer of protection against external elements.

The General Electric 12HGA11A51G features a 2.8 mm contact gap, which allows for efficient and reliable contact making and breaking. The coil winding is rated at 120V AC, 0.5 A, and 5.3 watts, with a 120V AC, 0.25 A, 2.2 watts pilot coil. The pilot coil simplifies the relay's operation by allowing it to be pre-energized, ensuring quick and smooth contact closing when the main coil is activated.

The relay's terminals are clearly marked and arranged in a numbered sequence for easy identification and wiring. The terminals are designed to accept 14-18 AWG wire sizes, and their copper alloy composition guarantees excellent electrical conductivity and a long service life.

The 12HGA11A51G relay comes with a built-in overload protection feature, which automatically trips the contacts when excessive current passes through them. This safety mechanism helps prevent damage to the contacts and the connected equipment.

Lastly, the General Electric 12HGA11A51G relay is RoHS compliant, which means it contains only lead-free materials. Additionally, it is UL listed, ensuring that it meets the strict safety and performance standards set by Underwriters Laboratories.

With its robust construction, efficient design, and reliable performance, the General Electric 12HGA11A51G is an excellent choice for various industrial and commercial applications, offering both function and durability in one compact and effective package.

The General Electric 12HGA11A51G relay is a commonly used electromechanical switching device. Here are some pros and cons that might help you decide if this relay is suitable for your specific application:
