Product description
Shipping

The Westinghouse EHB3100 is a rugged 100 A, three-pole circuit breaker built for everyday electrical work in panelboards, load centers, and distribution systems. Its bolt-on design provides a secure, dependable connection that stays in place even in vibration-heavy environments, making it a reliable choice for both maintenance and new installations.

  • Bolt-On Mounting — engineered for fast, solid installation with a secure hold in standard equipment enclosures.
  • Three-Phase Protection — 3 poles to safely interrupt three-wire, 3P circuits common in commercial and light industrial setups.
  • 480V Class — suitable for higher-voltage distribution in panelboards and electrical distribution networks.
  • 100 Amp Capacity — provides robust overcurrent protection for demanding equipment and circuits while maintaining control flexibility.
  • Original BOM Alignment — ideal for replacement projects where staying aligned with the original part number matters for service records and documentation.
  • Ready-to-Stock for Spares — a prudent addition to spare kits to minimize downtime and keep electrical assemblies compliant.
  • Trusted Brand — manufactured by Westinghouse, a long-standing name in electrical protection and reliability.

Ideal use cases

  • Replacing worn or failed breakers in panelboards, load centers, and distribution panels where a 3P, 480V, 100 A bolt-on solution is required.
  • Maintaining BOM accuracy on legacy installations by selecting the exact part number (EHB3100) for consistent documentation and service history.
  • Stocking a spare that covers maintenance windows and emergency repairs, reducing downtime for commercial and light industrial systems.
