Product Description P/N: QJH23B225
Description
The Siemens QJH23B225 is a three-pole molded case circuit breaker designed to protect electrical circuits against overloads and short circuits in commercial and industrial power distribution systems. It has a 225 A current rating, a 240 V AC voltage rating, and a 22 kA interrupting capacity at 240 V. Its thermal-magnetic trip mechanism and bolt-on mounting design make it suitable for compatible Siemens/ITE QJ-frame panelboards.

Information About QJH23B225
The Siemens QJH23B225 belongs to the QJ-frame family of molded case circuit breakers manufactured for low-voltage electrical distribution. It uses thermal-magnetic protection with long-time and instantaneous trip functions to respond to overload and short-circuit conditions. The breaker features three poles, bolt-on mounting, and load-side lug terminals for integration into compatible electrical panels. Its 22 kA interrupting rating at 240 V AC distinguishes it from standard-interrupting QJ models, making correct model and panel compatibility important during replacement or installation.
Key Features:
- 225 A Current Rating: Designed for high-current electrical distribution applications.
- 240 V AC Voltage Rating: Suitable for compatible low-voltage power distribution systems.
- Three-Pole Configuration: Provides circuit protection for compatible three-phase electrical systems.
- 22 kA Interrupting Capacity: Rated to interrupt fault current up to 22 kA at 240 V AC under specified conditions.
- Thermal-Magnetic Protection: Combines thermal overload protection with magnetic short-circuit protection.
- Long-Time and Instantaneous Trip Functions: Responds to sustained overloads and high-current fault conditions.
- Bolt-On Mounting: Designed for installation in compatible QJ-frame panelboards and electrical assemblies.
- Load-Side Lug Terminals: Supports electrical conductor connections within the manufacturer's specified wire ranges.
The Siemens QJH23B225 provides thermal-magnetic overcurrent protection for compatible commercial and industrial electrical distribution systems.
