LA3250PR - 250Amp Circuit Breaker

LA3250PR - 250Amp Circuit Breaker

The LA3250PR is a 250-amp, 3-pole Type LA fusible circuit breaker built around the LA3400PRF frame. If you're replacing a breaker that's already in service, those numbers are only part of the story. You'll also want to confirm the Type LA designation, LA3400PRF frame, 250A rating, three-pole arrangement, voltage, required interrupting capacity, and breaker configuration. Properly selected, professionally installed, and operated within its specified ratings, it's built to last.

Key Features and Benefits

• 250-amp rating for equipment specifically requiring a 250A breaker
• 3-pole configuration for matching compatible three-pole applications
• Type LA construction with an LA3400PRF frame
• TRI-PAC® DE-ION® fusible circuit breaker configuration
• 40°C rated
• Useful for maintaining compatible existing and legacy equipment when the required specifications match
• Defined dimensions and electrical ratings make it easier to check form, fit, and functional compatibility

Where It Works Best

The LA3250PR is intended for compatible existing and legacy electrical equipment calling for a 250A, 3-pole Type LA fusible circuit breaker with an LA3400PRF frame.

For replacement work, start with the catalog number, then put the specifications side by side with the breaker being removed. Check the 250A rating, three poles, Type LA designation, LA3400PRF frame, system voltage, required A.I.C. rating, 40°C rating, physical footprint, and TRI-PAC® DE-ION® configuration.
