Q1B230 - 30 Amp Circuit Breaker

Q1B230 - 30 Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, getting the details right matters. The Q1B230 is a 30-amp, 2-pole Type Q1B circuit breaker with a bolt-on design and thermal-magnetic operation. It carries a 10 kA.I.C. rating at 120/240 VAC and measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep. It also requires four spaces. Those details are especially important when you're trying to match a breaker already installed in compatible equipment. Rather than choosing on amperage alone, check the breaker type, number of poles, voltage, interrupting rating, mounting method, dimensions, and space requirements. For maintenance or replacement work in a legacy electrical system that calls for the Q1B230 configuration, this breaker provides the required form, fit, and function. It's a straightforward component built to last when used in the application for which it was designed.

Key Features and Benefits

• 30A, 2-pole design for equipment requiring this specific amperage and pole configuration.
• Rated 10 kA.I.C. at 120/240VAC.
• Bolt-on mounting is suitable for applications designed around the Type Q1B configuration.
• Uses a thermal magnetic trip mechanism for its intended circuit protection function.
• Requires four spaces, an important detail when checking the available installation footprint.
• Dimensions of 6.38" H x 1.5" W x 2.31" D make it easier to compare against an existing breaker before installation.
• A practical fit for maintenance work where matching the original breaker's electrical and physical characteristics is important.

Material Compliance and Certifications

• Material compliance details and specific agency certifications are not provided in the available specifications for the Q1B230. If your application requires a specific listing, certification, or material compliance standard, check the markings on the individual breaker and the applicable technical documentation before installation. Local electrical codes and equipment requirements should also be followed.

Where It Works Best

• The Q1B230 is intended for compatible electrical equipment that calls for a Type Q1B, 30-amp, 2-pole bolt-on thermal-magnetic circuit breaker with a 10kA I.C. rating at 120/240VAC. It is particularly relevant when maintaining legacy equipment, and the replacement breaker needs to match the existing installation as closely as possible in form, fit, and function.
