Meet the Square D EJB36040 40A 3-Pole Circuit Breaker — a purpose-built replacement designed for maintenance, retrofit, and replacement projects where exact compatibility matters. This unit is engineered to align with Square D specifications, delivering a reliable, drop-in option when you need to restore protective function without guessing at fit.

  • Amperage: 40 A
  • Poles: 3-Pole
  • Part Number: EJB36040

Why the part number matters: using the exact part number as your reference minimizes the risk of mismatches that can compromise circuit protection or extend downtime. The EJB36040 is the definitive reference for compatibility with Square D panels — always confirm fit and ratings before ordering to maintain the intended protection profile of your system.

Ideal use cases include:

  • Maintenance — replace a worn or failed 3-Pole 40A breaker to restore consistent circuit protection.
  • Retrofit — preserve your panel’s protection scheme while updating or reorganizing circuits with a like-for-like unit.
  • Replacement — swap in a compatible breaker to minimize service interruption and simplify future maintenance.

Practical guidance: before purchase, cross-check your panel model and the associated compatibility requirements. While the part number EJB36040 is the most reliable reference, verifying fit and ratings ensures you maintain your electrical system’s safety and reliability without surprises.
