Q1-270 - 70 Amp Circuit Breaker

Q1-270 - 70 Amp Circuit Breaker

Looking for a Q1-270 circuit breaker to match an existing installation? This Type Q1 plug-on thermal-magnetic breaker is rated at 70 amps, 2 poles, and 120/240 VAC, with a 10 kA I.C. rating. It's intended for compatible electrical equipment that was designed around the Q1 breaker configuration. That's an important distinction, especially with older equipment—a breaker can have the right amperage and still not be the right physical or electrical match. The Q1-270 measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep, and it requires four spaces. When you're maintaining a legacy system, details like these make a difference. Checking the part number, dimensions, connection style, voltage, poles, and interrupting rating can help determine whether this is the breaker your equipment calls for. When properly matched to its intended application, the Q1-270 provides the form, fit, and function needed to keep compatible equipment in service. It's a straightforward replacement solution built to last when correctly installed and used within its specified ratings.

Key Features and Benefits

• 70-amp, 2-pole design for equipment requiring this specific electrical configuration.
• Rated 120/240 VAC with a 10 kA.I.C. rating.
• Thermal-magnetic operation provides overcurrent protection within the breaker's rated application.
• Plug-on construction for compatible equipment that accepts Type Q1 breakers.
• Four-space configuration helps identify the correct physical fit for an existing installation.
• Clearly defined dimensions make it easier to compare the breaker with the unit being replaced.
• A practical choice for maintaining compatible legacy electrical equipment where the original form, fit, and ratings need to be preserved.
• Built to last when properly matched, installed, and operated within its intended application.

Material Compliance and Certifications

• Specific certification listings and material-compliance information were not included in the available specifications for the Q1-270. If your installation requires a particular certification or material standard, check the markings on the breaker and the applicable product documentation before installation. UL, CSA, RoHS, or other compliance should not be assumed unless specifically identified for the product.

Where It Works Best

• The Q1-270 70-amp 2-pole breaker is best suited for maintaining compatibility with legacy electrical systems designed for the Type Q1 plug-on configuration. It's a good fit for situations where keeping the existing equipment in service means finding a breaker with the correct physical dimensions and electrical characteristics rather than simply matching the amp rating.
