ED63A125 - 125Amp Motor Circuit Protector

ED63A125 - 125Amp Motor Circuit Protector

When you need a replacement magnetic motor circuit protector that matches the original equipment, the Siemens ED63A125 delivers the form, fit, and electrical ratings required for many existing commercial and industrial motor control applications. This 125 Amp, 3-pole SENTRON ED Frame magnetic-only circuit protector is designed for motor branch circuits where overload protection is provided separately, allowing it to respond quickly to short-circuit conditions while working as part of a coordinated protection system.

Rated for 600VAC, the ED63A125 provides an interrupting capacity of 18kA at 600 volts and 25kA at 480 volts, making it well suited for a wide range of industrial equipment, motor control centers, HVAC systems, pumps, compressors, conveyors, and manufacturing machinery.

Whether you're performing scheduled maintenance, replacing a failed unit, or keeping spare inventory on hand, this breaker helps preserve the original design and operation of compatible equipment without requiring changes to the system.
