GLNP250300 GLNP250300 Circuit Breaker, 250A, 3-Pole, 300V

The GLNP250300 circuit breaker is built for industrial electrical service, maintenance, and replacement projects. With a 250 A rating across 3 poles and a 300 V maximum, it delivers robust, three-phase protection for demanding operating environments while enabling fast and reliable disconnection when faults occur.

Who needs it: facilities with heavy, three-phase loads—including manufacturing lines, processing equipment, and complex distribution panels—that require dependable main or feeder protection with minimal downtime during service or retrofit projects.

• Three-pole configuration for balanced protection—simultaneously interrupts all three phases to prevent phase imbalance during faults, safeguarding motors and equipment.
• High-current capability—250 A capacity designed to handle large feeders and motor circuits common in industrial settings.
• Voltage rating up to 300 V—suitable for standard plant distribution networks, providing clear isolation for critical loads.
• Part-number-driven compatibility—verify fit by part number GLNP250300 to ensure correct mounting, electrical characteristics, and compatibility with your panel or bus system.
• Retrofit-friendly for replacements—streamlines upgrade and maintenance projects by matching common industrial protection schemes and reducing downtime when swapping aging devices.
• Industrial-grade reliability—designed to withstand demanding environments, delivering consistent protection and reducing nuisance trips in daily operation.

Practical use cases include protecting main feeders in factory floor distributions, safeguarding large motor circuits, and serving as a reliable replacement option when updating aging protection gear. When planning installation, ensure the device’s form factor and mounting scheme align with your panel, and confirm that the GLNP250300’s amperage and voltage ratings match your load requirements.
