E63A010 - 10Amp Motor Circuit Protector

E63A010 - 10 Amp Motor Circuit Protector

The E63A010 motor circuit interrupter is a 3-pole breaker designed for protecting motor branch circuits from short-circuit conditions in commercial and industrial electrical systems. Built on the E6-A ETI frame, this unit carries a 10-amp rating and is suitable for systems operating up to 600VAC. Motor circuit interrupters are commonly paired with external overload protection and are designed to respond quickly to fault currents while allowing normal motor startup current to pass without unnecessary tripping. This model includes line and load-side terminals, helping simplify installation in compatible equipment. Adjustable instantaneous trip settings allow electricians to match the breaker’s magnetic response to the needs of the motor circuit. Equipment built around the E6-A frame is still widely used in facilities today, and breakers in this class continue to play an important role in maintaining those systems. When the correct frame, ratings, and connection style are required, the E63A010 provides a form-fit-function replacement designed to work with existing equipment.
