Description
An essential component for industrial motor protection, this 50A E-Frame breaker utilizes magnetic-only trip technology to prevent damage from short circuits. It bolts securely into GE motor control centers and switchboards, and serves as a legacy predecessor to the TEC36050 series. Rated for 25kAIC at 480V, it features an adjustable instantaneous trip range between 156A and 360A, enabling precise coordination with motor starters to avoid nuisance tripping during startup.Specifications
