E63A003 - 3Amp Motor Circuit Protector

E63A003 - 3 Amp Motor Circuit Protector

The E63A003 motor circuit interrupter is designed for use in electrical distribution systems that require dependable short-circuit protection for motor circuits. Built on the E6-A ETI frame, this 3-pole, 3-amp unit rated for up to 600VAC is commonly used in industrial control panels, motor control centers, and equipment where precise instantaneous protection is required. The interrupter features adjustable instantaneous trip settings that allow technicians to match protection levels to specific motor starting characteristics and operating conditions. With both line-side and load-side terminals included, installation and replacement in compatible legacy systems is straightforward. Products in this class were built to last and are often selected when maintaining or servicing existing electrical infrastructure where the original frame type and electrical ratings must be preserved.
