LGA36250U31X - 250Amp Circuit Breaker

LGA36250U31X - 250Amp Circuit Breaker

When you’re matching a circuit breaker to an existing electrical system, the catalog number is only the beginning. The LGA36250U31X is a PowerPacT L-frame, 250A, 3-pole molded case circuit breaker designed for I-Line applications. Built to last, the LGA36250U31X is a practical choice for maintaining compatible electrical equipment when the form, fit, electrical ratings, trip characteristics, and connection style must match.

Key Features and Benefits

• 250A, 3-pole configuration: Provides the specified current rating and pole arrangement for compatible three-pole applications.
• PowerPacT L frame: Identifies the breaker family and frame configuration when checking compatibility with existing equipment.
• I-Line configuration: Designed with an I-Line connection on the line side for compatible I-Line electrical distribution equipment.
• MicroLogic 3.3 trip unit: Uses an electronic trip system with LI long-time and instantaneous protection functions.
• 600VAC maximum operating rating: Provides a clearly defined voltage specification for application checks.
• 80% continuous current rating: Matches applications requiring this specific continuous-current configuration.
