LD3350 - 350Amp Circuit Breaker Description
LD3350 - 350Amp Circuit Breaker
The LD3350 is a 350-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. It's a practical choice when you're maintaining existing electrical equipment and need to match a specific Type LD breaker rather than simply finding something with the same amp rating. When those electrical and physical specifications match the application, the LD3350 can serve as a form, fit, and functional replacement in compatible existing or legacy equipment.
Key Features and Benefits
- 350A, 3-pole Type LD configuration
- Thermal-magnetic circuit breaker with an interchangeable trip unit
- 40°C rated
- Includes load terminals
- Defined dimensions make physical compatibility easier to check

Where It Works Best
The LD3350 makes the most sense in existing and legacy electrical equipment that calls for a 350A, 3-pole Type LD thermal-magnetic breaker. Replacement work like this comes down to matching the details.
Start with the system voltage and required interrupting capacity. The LD3350 is rated 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC. From there, confirm the 8.25 "W x 10.75 "H x 4.06 "D footprint, interchangeable trip-unit configuration, and load-terminal arrangement against the breaker being replaced.
