Description

Mini circuit breaker, QO, 100A, 3 pole, 240VAC, 10kA, plug in

Features

  • Rated for a continuous 100-amp load at 240V, this high-amperage thermal-magnetic breaker is the primary solution for protecting large air conditioning units, heavy machinery, and sub-panel feeders. It delivers precision response times to both short circuits and sustained overloads, acting as a critical safeguard for your facility's most expensive electrical assets and sensitive industrial equipment.
  • Featuring the industry-leading Visi-Trip indicator, the breaker displays a highly visible red flag in the window the moment it trips. This intuitive design allows maintenance staff and electrical contractors to immediately pinpoint the faulted circuit among dozens of others, drastically reducing diagnostic time and getting your operations back online faster during a power failure.
  • Utilizing the patented QO plug-on connection system, this breaker snaps directly onto the bus bar without the need for time-consuming bolt-on hardware. This streamlined installation process reduces labor costs during new construction or system retrofits, while the high 10kA interrupting rating (AIR) ensures your electrical system remains fully compliant with modern NEC and UL safety requirements for light industrial and commercial applications.
