Information About JXD22B400
The JXD22B400 is part of the Siemens Type JXD2 low-voltage molded case circuit breaker family, engineered for dependable protection in industrial and commercial power systems. It features a JD-frame construction that supports high current ratings while maintaining mechanical strength and thermal stability. The thermal magnetic trip unit provides both long-time overload protection and instantaneous response to short-circuit conditions with an adjustable trip range. This circuit breaker is commonly used in switchboards, distribution panels, and DC power applications where high interrupting capacity and flexible wiring are required.
Key Features
- Two-pole breaker configuration: Designed for single-phase AC or DC systems requiring reliable disconnection of both conductors.
- 400 amp continuous current rating: Supports high-load feeder and distribution circuits in low-voltage applications.
- Thermal magnetic trip mechanism: Provides combined overload protection and instantaneous short-circuit interruption.
- Adjustable trip range: Configurable between 2000 and 4000 amps to match system fault coordination requirements.
- High interrupting capacity: Rated at 65 kA to safely interrupt severe fault currents.
- Wide conductor compatibility: Accepts load-side wiring from 3/0 AWG up to 500 kcmil for installation flexibility.
- Freestanding mounting design: Allows independent installation in electrical assemblies and distribution equipment.
- JD-frame construction: Ensures durability and consistent performance under demanding electrical conditions.
The JXD22B400 delivers the reliability and precision required for high-current single-phase AC and DC power protection in industrial and commercial electrical distribution systems.
