JB3225S | Circuit Breaker | 225A | 3-Pole | 600V

JB3225S Circuit Breaker is a robust industrial protection device engineered for three‑phase power systems, delivering a solid 225A current rating and a 600V maximum operating voltage. Ideal for maintenance, retrofit, and replacement projects where exact specifications matter.

Because compatibility matters in panel upgrades and system changes, use the JB3225S part number as your primary reference when checking fit and ratings. Always verify the breaker matches your busbar arrangement, frame size, and trip characteristics before ordering.

Specifications at a glance

• Amperage: 225A
• Poles: 3-Pole
• Voltage: 600V

Why this 3‑pole, 600V design is a smart choice

In three‑phase systems, a 3‑pole breaker ensures simultaneous shutdown of all live conductors, reducing the risk of arc flash and equipment damage. The 225A rating is well suited for industrial feeders and motor circuits that require solid overcurrent protection while accommodating legitimate startup currents.

Ideal use cases

• Routine maintenance and component replacement in manufacturing lines
• Retrofit projects upgrading power distribution to a 225A capacity
• Emergency spare for critical circuits in warehouses, facilities, and process plants

Practical tips for a smooth fit

Before purchase: confirm panel compatibility, busbar orientation, and mounting style matches your existing equipment. Keep the JB3225S on hand as part of your maintenance stock to minimize downtime when a fault occurs.
