Q221175BC - 175 Amp Circuit Breaker

Q221175BC - 175 Amp Circuit Breaker

The Q221175BC is a 175-amp, 2-pole molded-case circuit breaker used in your compatible electrical distribution equipment. It is a Type Q2, Q-Frame breaker with an I-Line plug-on connection and B-C phasing. The breaker is rated at 10 kA at 120/240 VAC and uses a thermal-magnetic trip. Physical size is 7.88 inches high, 3 inches wide, and 4.31 inches deep. For replacement work, it's worth checking all of these details against the breaker that's already in the equipment. The amp rating is only part of the match. Frame style, mounting, phasing, number of poles, voltage, dimensions, and interrupting rating also matter. The Q221175BC is a straightforward option for legacy equipment that was designed to use this particular breaker configuration. Its molded case construction is built to last when you install it correctly and use it within its stated ratings.

Key Features and Benefits

• 175-amp, 2-pole configuration for equipment that requires these ratings.
• Q2/Q-Frame design helps match the breaker to the correct equipment and mounting arrangement.
• I-Line plug-on connection for compatible I-Line applications.
• B-C phasing, an important detail to verify when replacing an existing breaker.
• Rated 10k AIC at 120/240VAC.
• Thermal-magnetic trip provides overload and short-circuit protection within the specified ratings.
• Well-suited to replacement and maintenance work where the original breaker specifications must be maintained.

Material Compliance and Certifications

• No specific material compliance or certification information is included in the available product data. Certification or listing status should therefore be confirmed from the markings on the breaker itself when required for the application. Installation should also meet the requirements of the equipment, applicable electrical codes, and the local authority having jurisdiction.

Where It Works Best

• This breaker is most useful when servicing older or legacy electrical equipment that already requires the Q221175BC configuration. In other words, this is about matching what's there rather than changing the system.
