Square D EJB26090 - 90 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Square D EJB26090, a 90A, 600V, 2-pole bolt-on molded case circuit breaker designed for dependable branch circuit protection in panelboards and loadcenters. Built to withstand demanding environments, this unit combines a secure bolt-on mounting with a precise thermal-magnetic trip mechanism to deliver consistent protection when it matters most.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing movement and wear in panels where vibration or routing complexity is common.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a wide range of loads and temperatures, minimizing nuisance trips while safeguarding sensitive circuits.
• 2-pole design ensures coordinated protection for both hot legs, improving safety and reliability in multi-wire branch circuits.
• 90A, 600V rating targets mid-size branch circuits with the robustness needed for residential, commercial, and light industrial applications.
• OEM-compatible compatibility with matching Square D loadcenters and panelboards helps streamline panel upgrades or replacements without re-engineering the field installation.

The EJB26090 excels where dependable overcurrent and short-circuit protection is essential. In residential settings, it protects main distribution paths and secondary circuits from overloads. In commercial environments, it supports lighting, outlets, and equipment feeders, delivering fast, predictable trip behavior to keep workers and assets safe. In light industrial spaces, it stands up to higher duty cycles while maintaining coordination with other protective devices, helping you meet code requirements and reduce downtime.

Why this breaker stands out is its combination of a secure mounting approach and a reliable thermal-magnetic trip profile. The bolt-on design minimizes looseness from thermal expansion and mechanical stress, while the trip unit provides quick response to overcurrent conditions without sacrificing precision. When you need a dependable, OEM-compatible solution for panelboards and loadcenters, the Square D EJB26090 is a thoughtful, field-proven choice.
