Information About HJXD63B300
The HJXD63B300 is a Siemens SENTRON Type HJXD6 molded case circuit breaker built on the JD frame for low-voltage electrical distribution applications. Its construction incorporates a non-interchangeable thermal-magnetic trip unit that provides long-time overload and instantaneous short-circuit protection without requiring an external electronic trip device. The breaker supports three-phase circuits, uses bolt-on mounting, and is rated for 600 volts alternating current or 500 volts direct current, with interrupting capacities of 35 kiloamperes at 600 volts alternating current and 65 kiloamperes at 480 volts alternating current. Siemens specifies the HJXD63B300 as a standard 40 degrees Celsius breaker with high breaking capacity, and the standard configuration is supplied without line or load lugs installed.
Key Features:
- 300-Ampere Rating: Provides a continuous current rating of 300 amperes for industrial and commercial distribution circuits.
- Three-Pole Configuration: Uses three poles for simultaneous protection and isolation of three-phase electrical circuits.
- 600-Volt Capability: Rated for operation up to 600 volts alternating current and 500 volts direct current.
- Thermal-Magnetic Protection: Uses a non-interchangeable thermal-magnetic trip mechanism for overload and short-circuit protection.
- High Interrupting Capacity: Provides 35 kiloamperes interrupting capacity at 600 volts and 65 kiloamperes at 480 volts alternating current.
- JD Frame Construction: Built on the Siemens JD frame and classified as a Type HJXD6 high-interrupting-capacity breaker.
- Bolt-On Mounting: Designed for bolted installation within compatible Siemens electrical distribution equipment.
- Standards Compliance: Meets UL 489 and IEC 60947-2 requirements specified by Siemens for this circuit breaker.
The HJXD63B300 delivers the reliability and precision required for overload protection, short-circuit interruption, and three-phase circuit isolation in industrial electrical distribution systems.
