LD3450 - 450Amp Circuit Breaker Description
LD3450 - 450Amp Circuit Breaker
The LD3450 is a 450-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. It’s a practical choice when you’re maintaining equipment designed around this specific LD configuration and need a replacement that closely matches the existing application. When properly selected for compatible equipment, installed correctly, and kept within its specified ratings, the LD3450 is built to last in the application it was designed for.
Key Features and Benefits
- 450A, 3-pole configuration for applications requiring these specific ratings
- Type LD thermal-magnetic circuit breaker
- Interchangeable trip unit
- 40°C rated
- Load terminals included
- Clearly defined dimensions make physical compatibility easier to check
- Well suited to form, fit, and functional replacement work in compatible existing and legacy equipment

Material Compliance and Certifications
The information provided identifies the LD3450 as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification details were supplied, so do not assume them.
Where It Works Best
The LD3450 makes the most sense in compatible existing and legacy electrical equipment that calls for a 450A, 3-pole Type LD breaker. It can be particularly useful when the objective is to keep an established electrical system matched to the breaker configuration it was designed to use.
Before installation, work through the ratings at the actual system voltage. At 600VAC, the interrupting rating is 25kA; at 480VAC, 35kA; and at 240VAC, 65kA. Confirm that the required interrupting capacity matches the application.
