LDC3400 - 400 Amp Circuit Breaker Description
LDC3400 - 400 Amp Circuit Breaker
With the LDC3400, the 400A rating is an obvious place to start, but it isn’t the only detail worth checking. This is a three-pole Type LDC thermal-magnetic circuit breaker with an interchangeable trip unit, a 40°C rating, and an HACR rating. Put those specifications together—the LDC type, 400A rating, three poles, trip configuration, electrical ratings, terminal arrangement, and footprint—and you have a much clearer way to judge form, fit, and functional compatibility. When correctly matched to the application, properly installed, and maintained within its stated ratings, the LDC3400 is built to last.
Key Features and Benefits
- 400A current rating: Provides a clear amperage specification to compare with the breaker being replaced and the equipment's requirements.
- Three-pole configuration: Matches equipment designed for this specific three-pole arrangement.
- Type LDC: An important identifier when looking for a form, fit, and functional match for existing LDC equipment.
- Interchangeable trip unit: Part of the LDC3400 configuration and an important detail to verify against the existing breaker.
- Thermal-magnetic design: Uses the specified thermal-magnetic protection configuration.
- Load terminals included: The supplied load-side connection arrangement is known before installation, making the compatibility check more straightforward.

Where It Works Best
The LDC3400 400A 3-pole circuit breaker is best suited to compatible existing and legacy electrical equipment that calls for a Type LDC thermal-magnetic breaker with an interchangeable trip unit. Because it includes load terminals, check the terminal configuration along with the breaker’s other specifications when matching it to equipment already in service.
