Q1-340 - 40 Amp Circuit Breaker

Q1-340 - 40 Amp Circuit Breaker

Looking for a Q1-340 circuit breaker to match an existing installation? This 40-amp, 3-pole Type Q1 breaker is a plug-on, thermal-magnetic unit rated at 10 kA I.C. at 240 VAC. It's intended for compatible electrical equipment that calls for this particular Q1 configuration. The breaker measures 6.38 inches high, 2.25 inches wide, and 2.31 inches deep and requires six spaces. When replacing a breaker in an existing or legacy system, those details matter. A 40-amp rating alone doesn't tell the whole story. You'll also want to match the number of poles, voltage, interrupting rating, connection style, physical size, and panel space requirements. For applications designed around the Q1-340, this breaker provides the form, fit, and function needed to maintain the original equipment configuration. It's a straightforward replacement option for the right application, built to last when properly installed, used, and maintained.

Key Features and Benefits

• 40-amp, 3-pole design for compatible three-pole applications.
• Type Q1 configuration for equipment designed around this breaker type.
• Plug-on connection provides the required fit for compatible equipment.
• Thermal-magnetic operation provides overload and short-circuit protection within the breaker's rated application.
• 10 kA I.C. at 240 VAC gives you a clear interrupting rating and voltage rating to match the existing installation.
• A six-space configuration helps determine whether the breaker will physically fit the intended panel.
• Defined dimensions make it easier to compare the Q1-340 with the breaker being replaced.
• Built to last when correctly matched to the application and properly installed and maintained.

Material Compliance and Certifications

• Specific material compliance information, certifications, and listings were not provided in the available specifications for the Q1-340. Because these requirements can depend on the equipment and application, they shouldn't be assumed.
• If a particular listing, certification, or material requirement is important for your installation, check the labeling on the breaker and the applicable technical documentation. The breaker should always be used in accordance with the equipment requirements and applicable electrical codes.

Where It Works Best

• The Q1-340 is best suited to existing and legacy electrical equipment designed to use a Type Q1, 40-amp, 3-pole plug-on circuit breaker with matching ratings and dimensions. It's particularly useful in replacement situations where maintaining the original form, fit, and function of the electrical equipment is important.
• Before determining compatibility, compare the Q1-340 with the breaker being replaced. Check the part number, Type Q1 configuration, 40-amp rating, three poles, 240 VAC rating, 10 kA.I.C., plug-on connection, six-space requirement, and physical dimensions. A match across these details provides a much clearer indication of suitability than amperage alone.
• Circuit breakers are safety-critical components, so final compatibility and installation should be verified by qualified electrical personnel in accordance with applicable codes and equipment requirements.
