Eaton | FDB4030BP10 | Circuit Breaker | 30A | 4-Pole

Introducing the Eaton FDB4030BP10 30A 4-Pole Circuit Breaker — a precise, reliable solution designed for 3-phase electrical systems that demand robust protection and safe, coordinated shutoff. This unit is ideal for maintenance, retrofit, and replacement projects where exact specifications matter, ensuring your panel continues to perform with confidence.

• Amperage: 30A
• Pole configuration: 4-Pole

Why this 4-Pole design matters

In 3-phase systems, a 4-pole breaker protects all live conductors plus the neutral, delivering a common-trip mechanism that instantly de-energizes every pole when a fault occurs. This enhances safety, simplifies diagnostics, and supports code-compliant shutdowns in complex electrical installations. Built by Eaton, a name trusted by professionals for durable protection devices, the FDB4030BP10 is engineered to perform reliably under demanding load conditions.

Ideal use cases

Use this circuit breaker for:

• Maintenance or service work on existing Eaton panels that specify the FDB4030BP10 part number
• Retrofits where a precise 30A, 4-pole protection solution is required
• Replacement of aging or faulty breakers in 3-phase applications with neutral connections

Careful compatibility and installation tips

Compatibility hinges on matching the exact part number and ratings, so confirm fit and ratings before ordering. The FDB4030BP10 is the best reference for ensuring seamless replacement within compatible Eaton panels. When installing, follow all local electrical codes and standards, and rely on a qualified electrician to verify panel compatibility, mounting, and wiring integrity.
