LDC3300L - 300 Amp Circuit Breaker Description
LDC3300L - 300 Amp Circuit Breaker
When you’re trying to match an LDC3300L, the 300A rating is a good starting point, but it’s not the only thing worth checking. This three-pole Type LDC circuit breaker uses thermal-magnetic protection and has an interchangeable trip unit. For existing and legacy equipment, that full combination—amperage, poles, trip configuration, terminals, ratings, and dimensions—matters most when determining form, fit, and function. When correctly matched, installed, and maintained within its stated ratings, the LDC3300L is built to last.
Key Features and Benefits
- 300A, three-pole configuration: One of the first details to check when comparing the LDC3300L with the breaker being replaced.
- Type LDC: A key identifier when working with equipment that calls for this breaker type.
- Thermal-magnetic design: Uses the specified thermal-magnetic protection configuration.
- Interchangeable trip unit: An important part of the breaker’s configuration that should be matched to the requirements of the existing equipment.
- Line and load terminals included: No guessing about the stated terminal configuration; both sides are included.
- 40°C rated: Another specification to verify against the intended application.
