Description

The Cutler-Hammer C300CG3 is a eutectic-type overload relay designed for motor protection in industrial applications. This Series A2 model provides reliable thermal overload protection for motors up to 30 amps, featuring a standard trip mechanism with three elements and one normally closed (N.C.) auxiliary contact. It is suitable for use in starters and contactors, particularly in environments requiring robust protection against overloads, phase loss, and imbalances. Key benefits include easy integration with Freedom and Citation series contactors, adjustable trip settings for precise calibration, and durable construction for long-term reliability in harsh industrial settings. Compared to electronic overload relays, the C300CG3 offers simplicity and cost-effectiveness without needing external power, though it may lack advanced diagnostics. Drawbacks include manual reset requirements and less flexibility in trip curves versus modern digital alternatives. Ideal for applications in manufacturing, HVAC systems, pumps, and conveyors, this relay ensures motor safety by interrupting power during overload conditions, reducing downtime and preventing damage. Its compact design facilitates easy installation in control panels, and it complies with UL standards for safety.
