QBHW2090 - 90Amp Circuit Breaker

QBHW2090 - 90Amp Circuit Breaker

The QBHW2090 is a 90-amp, 2-pole Type QBHW Quicklag circuit breaker made for compatible 120/240VAC electrical systems. It uses thermal-magnetic protection, so it responds to both prolonged overloads and short-circuit conditions. One specification worth noting is its 22kA interrupting rating at 120/240VAC, which makes it suitable for systems that call for this level of fault-current protection. The breaker uses a bolt-on connection rather than a plug-in design and is rated at 40°C. It's also HACR rated, an important consideration when the breaker is being used with qualifying heating, air-conditioning, or refrigeration equipment. If you're replacing an existing breaker, the details are what count. Check the QBHW2090 part number along with the amperage, number of poles, voltage, mounting style, and interrupting rating to make sure you're matching the requirements of your equipment.

• For any additional certification, listing, or material-compliance requirements, check the markings on the breaker and applicable manufacturer documentation for the specific unit.
  

Where It Works Best

• This breaker makes sense when the equipment specifically calls for a 90A, two-pole, bolt-on QBHW breaker rated for 120/240VAC and 22kAIC. Typical applications can include compatible commercial and industrial electrical distribution equipment, along with qualifying HVAC or refrigeration systems.
