LDB3500 - 500Amp Circuit Breaker

When you're matching the LDB3500 to an existing installation, don't stop at the 500A rating. The terminal configuration matters too. This Eaton Series C complete molded case circuit breaker comes with aluminum line and load terminals, giving you a specific connection arrangement to compare with the breaker already in service.

Key Features and Benefits

• 500A current rating: Provides the exact amperage specification to compare with the requirements of existing equipment.
• Three-pole configuration: Identifies the pole arrangement for compatible three-pole electrical applications.
• Series C, Type LDB: Important identification points when matching this breaker to existing or legacy equipment.
• L frame: Helps narrow the compatibility check to equipment designed for the specified breaker frame.
  
• 50–60 Hz frequency rating: Another electrical characteristic to confirm as part of the application review.
