LDB3450 - 450Amp Circuit Breaker

LDB3450 - 450Amp Circuit Breaker

When you're matching the LDB3450, check more than the 450A rating. This is an Eaton Series C complete molded case circuit breaker with a three-pole configuration, L frame, T186 trip type, and aluminum line and load terminals. Those terminal details are especially useful when comparing the breaker with the configuration already in your equipment. Put those specifications together, and you have a practical checklist for determining whether the LDB3450 matches the form, fit, and functional requirements of an existing or legacy installation. When correctly matched, installed, and maintained within its specified ratings, it's built to last.

Key Features and Benefits

• 450A current rating: Gives you the exact amperage specification to compare with the requirements of the existing equipment.
• Three-pole configuration: An important match point for equipment requiring a three-pole breaker arrangement.
• Series C LDB design: Series and breaker type are key identifiers when checking compatibility with an existing installation.
• L frame: Helps narrow the physical and configuration requirements during breaker identification.
• T186 trip type: Another specific detail to verify against the breaker being replaced and the equipment requirements.
• Line and load terminals: This LDB3450 configuration includes terminals on both the line and load sides.
