Shipping
Meet reliability for demanding power layouts: the Siemens CK3B125 circuit breaker delivers precise overcurrent protection for 3-pole, 125A circuits in 600V systems. Built for maintenance, retrofit, and replacement projects, it helps keep commercial and light industrial panels safeguarded against overloads and short circuits.
Key specifications
- Amperage: 125 A
- Poles: 3-Pole
- Voltage rating: 600 V
- Part reference for compatibility: CK3B125
- Applications: maintenance, retrofit, replacement
Why this Siemens CK3B125 stands out
The CK3B125 is designed to drop into Siemens-compatible panels and distribution gear that require a 3-pole, 125-amp, 600-volt protection device. Its part-number–driven compatibility makes ordering straightforward and reduces the risk of mismatch in multi-panel setups. This makes it an ideal choice for:
- Upgrading existing feeders to 125A protection in three-phase distributions
- Replacing aging or damaged breakers in service entrances and motor control centers
- Retrofits that unify protection across a facility to simplify maintenance and procurement
Practical guidance for installation and use
Before ordering, confirm fit and ratings against your panel and equipment. The CK3B125 is the best reference for compatibility, so keeping the exact part number handy—CK3B125—helps ensure a seamless replacement or retrofit.
