ED63A025 - 25Amp Motor Circuit Protector

ED63A025 - 25Amp Motor Circuit Protector

When maintaining or repairing an existing Siemens motor control system, the Siemens ED63A025 provides the ratings and configuration needed for a compatible replacement. This 3-pole, 25 Amp magnetic-only motor circuit protector is part of the trusted Siemens SENTRON ED Frame family and is designed for motor branch circuits where overload protection is supplied by a separate overload relay. Rather than combining overload and short-circuit protection into a single device, the ED63A025 delivers instantaneous magnetic trip protection to help protect against short circuits while allowing the external overload relay to perform overload protection. This design makes it well suited for industrial motor control systems that were originally engineered with magnetic-only motor circuit protectors. Whether you're replacing a failed unit during routine maintenance or keeping legacy equipment in service, the Siemens ED63A025 offers the form, fit, and functional compatibility needed for many existing installations. Built to last, it helps support the continued operation of compatible motor control equipment.
