LDB3450W - 450Amp Circuit Breaker Description
LDB3450W - 450Amp Circuit Breaker
The LDB3450W has one detail you'll want to note right away: it ships without terminals. When you're matching a breaker to existing electrical equipment, that configuration can be just as important as amperage or pole count. For replacement work, the smartest approach is to compare the whole configuration—catalog number, Series C and LDB designations, L frame, T186 trip, electrical ratings, dimensions, and the fact that terminals are not included—with the equipment requirements. Correctly matched, installed, and maintained within its stated ratings, the LDB3450W is built to last.
Key Features and Benefits
- Supplied without terminals: A defining configuration detail to verify before determining whether this breaker fits the existing application.
- 450A current rating: Clearly identifies the breaker amperage for comparison with the equipment requirements.
- Three-pole design: Provides the specified pole arrangement for compatible three-pole installations.
- Series C, Type LDB: Two important identifiers when matching the breaker to existing or legacy electrical equipment.
- L frame: Helps confirm the required breaker frame and physical configuration.
- T186 trip type: Another specific match point that should agree with the requirements of the installation.
- 50–60 Hz frequency rating: Gives you another electrical specification to verify against the system.

Material Compliance and Certifications
The LDB3450W is UL 489 certified, giving you a specific certification to check when UL 489 compliance is required for the equipment or installation. The supplied specifications do not include CSA, IEC, RoHS, REACH, terminal-material, or other material-compliance information, so do not assume those details.
Where It Works Best
The LDB3450W 450A 3-pole molded case circuit breaker is best suited to compatible existing and legacy electrical equipment that calls for a Series C Type LDB complete breaker with an L frame and T186 trip type. The "W" configuration is particularly important here because this model is specified without terminals. Confirm that detail, along with the electrical ratings, before installation.
