ED63A040 - 40Amp Motor Circuit Protector

ED63A040 - 40Amp Motor Circuit Protector

When you're maintaining or replacing components in an existing Siemens motor control system, the Siemens ED63A040 offers a dependable, like-for-like solution designed to keep operations running smoothly. This 3-pole, 40 Amp magnetic-only motor circuit protector is built for Siemens SENTRON ED Frame applications where motor overload protection is handled separately, and the breaker is responsible for rapid response to short-circuit conditions. Its magnetic-only trip design makes it a practical fit for motor branch circuits in commercial and industrial environments that rely on coordinated protection schemes. Rated for 600VAC, with interrupting ratings of 18kA at 600VAC and 25kA at 480VAC, the ED63A040 is suited for demanding electrical systems where proper coordination and compatibility matter. It comes equipped with load lugs (LN1E100) and supports 10 AWG through 1/0 AWG copper or aluminum conductors, making installation straightforward in compatible Siemens equipment.
