LDB3350W - 350Amp Circuit Breaker Description
LDB3350W - 350Amp Circuit Breaker
When you’re trying to match the LDB3350W, don’t stop at the 350A rating. A few details set this breaker apart, and the 115V Mil-Spec HI shock shunt trip with 50-inch pigtail leads is one of them. This is an Eaton Series C LDB molded case circuit breaker built on an L frame, with three poles and a T186 trip type. The LDB3350W is built to last when properly matched, installed, and maintained. For legacy equipment in particular, checking the whole configuration—rather than relying on amperage alone—is the sensible way to determine form, fit, and functional compatibility.
Key Features and Benefits
- 350A, three-pole configuration: The basic electrical configuration to verify first when matching an existing breaker.
- Series C LDB design: The series, breaker type, and frame help narrow compatibility with existing equipment.
- L frame: An important part of identifying the correct physical and functional configuration.
- T186 trip type: Another specific detail to compare with the breaker being replaced.
- 50–60 Hz frequency rating: Provides a clearly defined frequency range for application matching.
