Description
Built for industrial applications, the Siemens EF3A030 provides dedicated instantaneous short-circuit defense. This 30A protector uses an adjustable magnetic trip (80-270A) to coordinate with overload relays. Featuring a bolt-on configuration, it mounts into legacy Siemens and I-T-E panelboards. For modern upgrades, this E-Frame device crosses over to the ED63A030. Rated for 600VAC (14kAIC at 480V), the magnetic-only architecture prevents nuisance tripping during motor startups.Specifications
