Product description
Shipping

Engineered by Westinghouse, the RJ2090 is a precision-rated circuit breaker designed for robust protection in demanding electrical systems. This 90A, 2-pole device delivers dependable, trip-ready performance for maintenance, retrofit, and replacement projects where exact specs matter.

  • Exact compatibility—RJ2090 is the reference part number for matching Westinghouse panels and compatible equipment.
  • Dual-pole protection—two-pole design interrupts both supply lines, preserving system safety in multi‑wire circuits.
  • Voltage rating—rated up to 600V, suitable for a range of industrial and commercial applications.
  • Ampacity—90A continuous rating provides protection for medium-load circuits while enabling safe operation.
  • Easy sourcing—keep on hand as a maintenance or replacement spare to minimize downtime.

Important: Confirm fit and ratings before ordering. The RJ2090 part number is your best reference for compatibility, ensuring you don’t mismatch amperage, pole count, or voltage rating in your panel or load center.

  • Maintenance and service when a breaker fails or when upgrading to a validated spec in Westinghouse panels.
  • Retrofit projects where older gear needs an exact 90A, 2‑pole, 600V replacement.
  • Spare provisioning for field service teams to reduce downtime on critical systems.
  • Industrial or commercial electrical installations requiring reliable overcurrent protection at 90A.

Compared to substitutes, using the RJ2090 guarantees matching mechanical fit, trip characteristics, and electrical ratings, minimizing compatibility risks and panel downtime.

Who it's ideal for: Electricians, facility managers, and maintenance crews who work with Westinghouse panels or systems that require a precise 90A, 2-pole, 600V circuit breaker.

Equip your toolbox with the Westinghouse RJ2090 today and enjoy straightforward replacement, reliable protection, and peace of mind across your electrical infrastructure.
