LD3450L - 450Amp Circuit Breaker Description
LD3450L - 450Amp Circuit Breaker
The LD3450L is a 450-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. It comes with both line and load terminals and is rated for operation at 40°C. If you're matching a breaker for equipment already in service, check the electrical ratings closely: 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC. It's also HACR rated. Properly matched to the application, installed correctly, and kept within its specified ratings, it's built to last for the job it was designed to do.

The available specifications identify the LD3450L as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance details were provided, so do not assume them.
Where It Works Best
The LD3450L makes the most sense in compatible existing and legacy equipment that requires a 450A, 3-pole Type LD breaker. For replacement work, focus on the electrical and physical details rather than amperage alone.
Check the required system voltage against the appropriate interrupting rating—25kA at 600VAC, 35kA at 480VAC, or 65kA at 240VAC. From there, confirm the Type LD configuration and interchangeable trip-unit requirements.
