Built to meet the needs of panels that require three independent poles, this breaker delivers dependable overcurrent protection for multi-wire or three-phase 240V circuits.

Core details at a glance

• Pole configuration: 3-Pole
• Voltage rating: 240V
• Compatibility reference: The part number JA3225WK is the best reference for finding a precise fit in your panel

Why this Westinghouse JA3225WK stands out

For those upgrading or repairing electrical panels, the JA3225WK delivers targeted, reliable protection exactly where you need it. Its 3-pole design is ideal for 240V circuits that require simultaneous protection across multiple conductors, helping to prevent imbalances and reduce the risk of overcurrents in complex electrical setups.

Who should consider this model

• Technicians performing panel retrofits or replacements in commercial or residential settings that require a 3-pole, 240V solution
• Maintenance teams refreshing aging equipment where a precise JA3225WK fit is required
• Electrical installers seeking a straightforward, compatible replacement for panels that specify a 3-pole 240V configuration

How to verify compatibility and plan installation

• Refer to your panel labeling and confirm the required pole count (3) and voltage rating (240V)
• Use the JA3225WK part number as the primary reference to ensure exact fit and terminal configuration
• Before ordering, double-check the panel’s compatibility with a 3-Pole 240V breaker and confirm any interrupting rating requirements
• Plan installation with the main power OFF and follow all local electrical codes; if in doubt, consult a licensed electrician

Practical use cases and benefits

In practice, this breaker supports reliable protection in systems where a three-pole, 240V solution is necessary—such as multi-wire circuits or three-phase equipment protection—while offering a straightforward path to retrofit or replace aging components. By pairing exact specifications with a clear compatibility reference, it reduces guesswork and speeds up project timelines.

Notes: Always confirm fit and ratings before ordering. The JA3225WK part number is the most reliable reference for compatibility to avoid mismatches and ensure safe, compliant operation.
