General Electric | MB513 | Circuit Breaker | 225A | 3-Pole | 480V | Plug-In

Meet the General Electric MB513 circuit breaker — a robust, plug-in solution engineered for dependable protection in high-demand electrical systems. With a 225A rating and a 3-pole configuration at 480V, this breaker is designed for three-phase circuits where reliable overcurrent protection and quick replacement matter most. Designed for maintenance, retrofit, and replacement projects, the MB513 is built to match specific GE panel requirements, helping keep downtime to a minimum.

• Amperage: 225A
• Poles: 3-Pole
• Voltage: 480V
• Mounting: Plug-In

Why the MB513 stands out

The MB513 is more than a standard breaker. Its plug-in design is purpose-built for compatible GE panels, enabling fast swaps during routine maintenance or when upgrading to a higher-capacity protection scheme. The triple-pole construction ensures synchronized interruption across all three legs of a 3-phase system, guarding motors, transformers, and equipment from overloads and short circuits with consistent trip performance.

Ideal use scenarios

• Industrial control panels and manufacturing lines operating on 3-phase 480V systems
• Retrofits in aging GE panels that require a direct MB513-compatible replacement
• New or upgraded installations where robust 225A protection is appropriate for heavy loads

Installation and compatibility notes

Before ordering, confirm fit and ratings against your panel’s documented requirements. The part number MB513 is the most reliable reference for compatibility, ensuring you’re selecting the exact plug-in breaker that your GE panel expects. This is a plug-in solution, so verify that your enclosure supports a three-pole, 480V configuration and that the bus structure matches the MB513 profile. For a safe, long-lasting installation, follow all manufacturer wiring guidelines and have a licensed electrician perform the replacement.

How this breaker helps you manage risk and uptime

• Direct, plug-in replacement minimizes downtime and panel downtime during maintenance or retrofit projects
• Three-pole design provides balanced protection across all phases, reducing the risk of uneven fault conditions
• High-current capability (225A) supports demanding loads common in commercial and industrial settings

Practical tips for getting the most from your MB513

• Prepare your panel model and confirm it supports 480V, 3-pole plug-in breakers to ensure seamless compatibility
• Keep the panel’s documentation handy to verify that MB513 is the exact replacement part you need
• Schedule replacement during a planned maintenance window to minimize production impact
