Siemens E1SED43B050 Circuit Breaker is a purpose-built protective device for industrial electrical service, maintenance, and replacement projects. With a three-pole design for three-phase systems and a 50 A rating, it delivers reliable overcurrent protection at 480 V across all three phases.

Key benefits and what makes it unique:

  • Part-number-driven compatibility: Use the exact part number E1SED43B050 to confirm fit in your Siemens-compatible panels and assemblies. This isn’t a generic breaker—it's a Siemens component designed to align with Siemens electrical ecosystems.
  • Three-pole, 480 V protection: Engineered for three-phase circuits common in industrial settings, providing synchronized protection across all phases to prevent unbalanced faults that can damage equipment.
  • 50 A capacity for medium-load circuits: Ideal for motors, pumps, drives, and control circuits that require solid protection without nuisance trips in normal operation.
  • Industrial-grade reliability: Built to withstand the rigors of maintenance and field replacements, reducing downtime during service windows.
  • Simple replacement workflow: Designed to slot into existing Siemens panel configurations, minimizing modification and enabling faster maintenance cycles.

Practical use cases:

  • Replacing a failed circuit breaker in a three-phase industrial panel during planned maintenance or after a fault event.
  • Protecting motor drives, conveyors, and compressors on manufacturing lines that run on 480V three-phase service.
  • Serving as a dependable service disconnect in machine cells or processing equipment where reliable trip protection is critical.

How to verify compatibility:

Always verify fit by part number and your application requirements. If you’re unsure about cross-reference or compatibility, the seller can assist—you can message us to confirm that E1SED43B050 matches your panel, bus type, and trip characteristics.
