LD3350L - 350Amp Circuit Breaker Description
LD3350L - 350Amp Circuit Breaker
The LD3350L is a 350-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit, built to meet the specifications of your compatible existing electrical equipment. Its interrupting ratings are 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, and it carries a 40°C rating along with an HACR rating. When properly selected for compatible equipment, installed correctly, and operated within its specified ratings, the LD3350L is built to last in the application it was designed to serve.

Material Compliance and Certifications
The supplied specifications identify the LD3350L as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided, so do not assume those details from the Type LD designation or electrical ratings.
Where It Works Best
The LD3350L is a good fit for maintenance and replacement work involving compatible existing or legacy equipment that requires a 350A, 3-pole Type LD breaker with an interchangeable trip unit.
When checking the match, start with the electrical ratings. Confirm the application matches the breaker's 350A rating and the required interrupting capacity at the system voltage. After that, compare the 8.25 "W x 10.75 "H x 4.06 "D dimensions and make sure the line-and-load terminal arrangement suits the installation.
