The Eaton Cutler-Hammer JD3250 is a Series C, J-Frame molded case circuit breaker designed to provide reliable thermal magnetic protection in demanding electrical environments. This three-pole breaker features a 250-amp continuous current rating and operates at up to 600V AC. It utilizes a non-interchangeable, fixed thermal and magnetic trip unit with long-time and instantaneous (LI) functions to protect against overloads and short circuits. The breaker offers a standard interrupting capacity of 35kA at 480V and is configured for a bolt-on connection type. It is built for a standard 40°C ambient operating temperature and includes load side lug terminals. Always verify panel compatibility, exact source, physical condition, availability, and lead time directly on your written quote before finalizing any purchase.
Application context: Designed for heavy-duty industrial applications requiring thermal magnetic protection.
