The Square D EJB26100 is a molded-case circuit breaker (MCCB) from Square D's EJB frame series, rated 2-pole, 100A, 600/347V, 25kA interrupting capacity with a bolt-on mounting. As a commercial/industrial-grade MCCB, it is designed to mount in Square D panelboards and switchboards that accept EJB-frame bolt-on breakers — not residential loadcentres.

  • Suited for commercial and industrial panelboards (600V class) configured for EJB-frame breakers
  • Common applications include branch circuit and feeder protection in manufacturing, commercial buildings, and utility distribution panels
  • Not compatible with QO or Homeline residential loadcentres

Send us your panelboard model number and we'll confirm fitment — contact our team or visit one of our Calgary, Edmonton, or Vancouver counters.

The EJB26100 has a 25kA interrupting capacity at 600/347V, making it well suited for commercial and light industrial panelboards and switchboards operating at 600V class. Always verify that your panel's available fault current does not exceed 25kA at the point of installation.

The EJB frame series is considered a legacy/hard-to-find product line. Northern Breaker Group specializes in obsolete and discontinued breakers — we maintain stock and can source EJB-frame breakers through our supply network. Contact us for current availability.

Not necessarily — frame series, bolt-on mounting configuration, and panelboard compatibility must all match. The EJB26100 must replace an existing EJB-frame breaker in a panel rated to accept it. Swapping in a different frame (e.g., KAL, FAL) is not interchangeable. Share your panel model with our team and we'll confirm the correct replacement.
