LDC3450 - 450 Amp Circuit Breaker Description
LDC3450 - 450 Amp Circuit Breaker
The interchangeable trip unit is a useful detail when you’re trying to identify an LDC3450 in existing equipment. From there, the other specifications give you a pretty clear checklist. The LDC3450 is a 450A, three-pole Type LDC thermal-magnetic circuit breaker, rated at 40°C and HACR-rated, with load terminals included. Review the full configuration—450 amps, three poles, LDC type, trip arrangement, load terminals, interrupting ratings, temperature rating, and footprint. When those details match the application, and the breaker is correctly installed and maintained within its stated ratings, the LDC3450 is built to last.
Key Features and Benefits
- Interchangeable trip unit: An important identifying feature when matching the LDC3450 to an existing breaker configuration.
- 450A current rating: Provides a clear amperage specification to check against equipment requirements.
- Three-pole configuration: Designed for applications that require this exact pole arrangement.
- Type LDC: One of the primary details to verify when replacing an LDC breaker in existing or legacy equipment.
- Thermal-magnetic design: Uses the specified thermal-magnetic protection configuration.
- Load terminals included: Helps remove guesswork when checking the load-side connection arrangement.

Material Compliance and Certifications
The supplied specifications identify the LDC3450 as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for this exact part number.
Where a particular certification or material standard is required, verify that requirement for the exact LDC3450 before installation.
Where It Works Best
The LDC3450 450A 3-pole circuit breaker is best suited to compatible existing and legacy electrical equipment that calls for a Type LDC thermal-magnetic breaker with an interchangeable trip unit. This configuration includes load terminals, so connection details should be part of the comparison with the breaker currently installed.
