Information About HHJXD63B400
The HHJXD63B400 belongs to the Siemens Sentron family of low-voltage molded case circuit breakers and uses a JD-frame configuration. Its thermal-magnetic trip mechanism responds to overload and short-circuit conditions to interrupt current within its specified operating limits. The high-interrupting-capacity design provides up to 100 kA interrupting capacity at 480 V AC and 50 kA at 600 V AC, depending on the applicable product configuration and rating data. The breaker is supplied without factory-installed terminal lugs, so compatible connection hardware must be selected separately for the installation.
Key Features:
- 400 A Current Rating: Supports high-current power distribution and equipment protection applications.
- 600 V AC Voltage Rating: Designed for compatible industrial and commercial electrical systems.
- Three-Pole Configuration: Disconnects all three phases in compatible three-phase power circuits.
- Thermal-Magnetic Trip: Provides overload and short-circuit protection through thermal and magnetic tripping mechanisms.
- High Interrupting Capacity: Provides interrupting ratings of up to 100 kA at 240 V AC and 50 kA at 600 V AC, according to the applicable configuration.
- JD Frame Design: Uses the Siemens JD-frame molded case breaker platform.
- Fixed Trip Unit: Features a non-interchangeable thermal-magnetic trip unit with a 2,000–4,000 A instantaneous trip range.
- Bolt-On Connection: Supports bolt-on installation in compatible electrical distribution equipment; terminal lugs are not included.
The Siemens HHJXD63B400 delivers high-capacity circuit protection for compatible industrial and commercial electrical distribution systems.
