Description
Built for heavy-duty motor protection, the EF3A050 utilizes a magnetic-only trip mechanism to interrupt short circuits instantly. This 50-amp unit works alongside separate overload relays in industrial motor control circuits. It installs into legacy ITE and Siemens motor control centers and panelboards. For upgrades, the ED63A050 is the recommended replacement. Delivering up to 18kAIC at 240VAC, this E-frame breaker features an adjustable magnetic trip range. Lugs are not included.Specifications
