Product description
Shipping
Meet the Siemens QJ23B125A01 Circuit Breaker—a robust 125A, 3-Pole device designed for 240V systems. With a 10kA interrupting capacity and bolt-on mounting, this breaker delivers dependable overcurrent protection for demanding maintenance, retrofit, and replacement projects. Its precise specs and durable construction make it a trusted choice for keeping 3-phase electrical circuits safe and reliable.
Key specifications
- Amperage: 125A
- Poles: 3-Pole
- Voltage: 240V
- Interrupting Capacity: 10kA
- Mounting: Bolt-On
Why these specs matter: The 125A rating is well-suited for protecting feeders and branch circuits in 3-phase 240V panels, while the 10kA interrupting capacity provides a strong margin against high fault currents. The bolt-on design offers secure, vibration-resistant installation in compatible Siemens panels, contributing to long-term protection and easier service access.
Ideal use cases
- Maintenance and service replacements that require exact Siemens QJ series parts
- Retrofits upgrading equipment to a safer, higher-capacity 125A protection in 3-phase systems
- New installations in commercial or industrial settings where a reliable bolt-on breaker is preferred
Compatibility note: Confirm fit and ratings before ordering. The part number QJ23B125A01 is the best reference for ensuring compatibility with your panel or enclosure.
