Cutler-Hammer 1318-111 AC Contactor Coil 600V 60Hz

The Cutler-Hammer 1318-111 is a discontinued AC coil designed for use in magnetic contactors and starters, particularly in industrial control systems. This coil operates at 600V AC with a 60Hz frequency, and is also rated for 550V at 50Hz, making it versatile for various electrical setups in manufacturing, HVAC, and automation environments. Key features include a robust molded construction for durability in harsh conditions, easy installation with spade terminals, and reliable electromagnetic performance to actuate contactor mechanisms. Advantages over similar products include its compatibility with legacy Cutler-Hammer Citation Line contactors, providing a cost-effective replacement option for maintaining older equipment without full system upgrades. However, as a discontinued item, availability is limited to surplus or refurbished stock, which may lead to higher costs or sourcing challenges compared to modern equivalents from Eaton (which acquired Cutler-Hammer). Benefits include high voltage tolerance for heavy-duty applications, reducing the risk of coil burnout in high-power circuits. Drawbacks encompass potential obsolescence, lack of modern efficiency improvements, and the need for periodic inspection due to age-related wear. Ideal for retrofitting in motor control centers, pumps, and conveyor systems where precise switching is required. Overall, this coil offers dependable performance for legacy systems but may require adaptation for newer installations.
