Information About HJXD63B400
The HJXD63B400 is a Siemens Sentron Series circuit breaker classified under the HJXD low-voltage family. It is engineered as a three-pole molded case circuit breaker for three-phase electrical systems requiring high current capacity. The unit uses a non-interchangeable thermal magnetic trip unit to provide protection against overloads and short circuits. It is commonly installed in industrial and commercial distribution panels where UL-listed reverse-fed capability and bolt-on mounting are required.
Key Features
- Sentron Series Design: Built to Siemens Sentron standards for industrial low-voltage distribution systems.
- 400 Amp Rating: Supports high-load feeders and main distribution circuits.
- 3-Pole Configuration: Designed for balanced three-phase power systems.
- Thermal Magnetic Trip Unit: Provides combined overload and instantaneous short-circuit protection.
- High Interrupting Capacity: Rated to interrupt fault currents up to 65 kA at 480 V.
- Bolt-On Mounting: Ensures secure mechanical and electrical installation.
- UL Listed for Reverse Feed: Approved for applications requiring reverse-fed configurations.
The HJXD63B400 delivers the reliability and precision required for high-capacity protection in Siemens Sentron three-phase electrical distribution systems.
