LDB3500W - 500Amp Circuit Breaker

LDB3500W - 500Amp Circuit Breaker

One thing you’ll want to notice right away about the LDB3500W is that it’s supplied without terminals. That may sound like a small detail, but when you’re matching a circuit breaker to existing equipment, the connection arrangement belongs on the checklist along with amperage, poles, frame, and trip type. Those clearly defined specifications make it easier to compare the LDB3500W with the breaker and equipment already in service. Rather than relying on the catalog number alone, verify the complete set of electrical, physical, and connection requirements. When correctly matched, installed, and maintained within its specified application, the LDB3500W is built to last.

Key Features and Benefits

• 500A amperage rating: Gives you a clear current rating to compare against the requirements of the existing equipment.
• Three-pole configuration: An essential identification point for compatible three-pole applications.
• Series C LDB design: The series and breaker type provide useful information when matching an existing or legacy breaker installation.
• L frame: Frame designation matters for both physical and functional compatibility, so it should be checked rather than assumed.
• T186 trip type: Another specific part of the LDB3500W configuration to compare with the breaker being replaced.
• Supplied without terminals: An important distinction to know before installation, especially when checking the connection requirements of existing equipment.
