The Eaton Cutler-Hammer HJD3250 circuit breaker represents a critical component in electrical distribution systems. This molded case model is built to sustain a rated current of 250 amps and can operate at a maximum voltage of 600 volts AC, as well as 250 volts DC. It falls under the HJD type classification and has a specified trip type identified as T186.
This circuit breaker is structured with three poles and sits within a J frame size, allowing compatibility with various panel setups. It is designed for high interrupting capacities, rated at 65 kAIC for 480 volts AC and 100 kAIC for 240 volts AC, which reflects its capability to safely clear faults.
Operational requirements dictate that the environment must not exceed 80% humidity to avoid condensation-related issues, thus ensuring long-term reliability. Furthermore, the HJD3250 is suitable for installations at altitudes up to 1000 meters above sea level. The terminals are made from aluminum, facilitating lower resistance connections, contributing to overall performance and efficiency in the field.
