Q1B315 - 15 Amp Circuit Breaker

Q1B315 - 15 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, getting the right fit matters just as much as matching the amp rating. The Q1B315 is a 15-amp, 3-pole, Type Q1B thermal-magnetic circuit breaker with a bolt-on design. It is rated 10 kA I.C. at 240 VAC and is intended for electrical equipment designed to use this specific breaker style and configuration. The breaker measures 6.38 inches high, 2.25 inches wide, and 2.31 inches deep, and it requires six spaces. That makes it important to check the physical layout of your equipment and its electrical ratings before making a replacement. For maintenance of compatible legacy electrical systems, the Q1B315 provides the familiar form, fit, and function needed to keep the original equipment configuration intact. It's a straightforward, built-to-last component for applications where the Q1B315 specifications are the correct match.

Key Features and Benefits

• 15-amp rating for applications designed around a 15A breaker.
• Three-pole configuration for circuits requiring three-pole protection.
• Bolt-on design for compatible Q1B electrical equipment.
• Thermal-magnetic operation provides overcurrent protection using thermal and magnetic trip functions.
• Rated 10k A.I.C. at 240VAC.
• Requires six spaces, an important detail when checking physical compatibility.
• A practical fit for legacy electrical systems that call for the Q1B315 configuration.
• Built to last when installed in the correct application and used within its specified ratings.

Material Compliance and Certifications

• Specific certification, listing, and material compliance information was not provided with the available Q1B315 specifications. If your installation has specific compliance or certification requirements, check the markings on the breaker and the documentation for the equipment to be installed. A qualified electrical professional should verify that the breaker meets the application's requirements.

Where It Works Best

• The Q1B315 circuit breaker makes the most sense for existing electrical equipment designed for Type Q1B bolt-on breakers. It's especially useful in maintenance and replacement situations where keeping the original breaker configuration is important.
• Before replacing an existing breaker, check the details rather than going by amperage alone. The application should match the 15A rating, three-pole configuration, Q1B type, bolt-on mounting, 240VAC rating, 10k A.I.C. rating, physical dimensions, and six-space requirement.
