The Siemens BQ2B090 is a 90A, 240V, 2-pole bolt-on molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters.

Built to withstand the demands of busy electrical environments, this breaker uses secure bolt-on mounting to deliver a rigid, vibration-resistant bus connection. That solid interface reduces connection looseness over time, helping maintain consistent protection where it matters most.

  • Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining a fast magnetic trip for short circuits with a thermal element that adapts to temperature changes, reducing nuisance trips and preserving system reliability.
  • OEM-compatible, plug-and-play: Designed to work with matching Siemens OEM load centers and panelboards, enabling straightforward upgrades or replacements without adapters or modifications.
  • Versatile 2-pole design: 90A at 240V provides robust protection for a dedicated branch circuit or a feed to a subpanel in residential, commercial, or light industrial installations.
  • Bolt-on convenience: Simple installation that maintains a tight bus connection even in panels exposed to vibration or movement.
