Schneider Electric QO230 Miniature Circuit Breaker, 30A, 2 Pole, 120/240VAC, 10kA

Description

Features

• The QO230 is a premium 2-pole, 30-Amp Miniature Circuit Breaker designed for Square D QO load centers. It provides simultaneous overcurrent protection for both "hot" legs of a 240V circuit, making it the industry standard for protecting residential and commercial equipment like electric water heaters, small central air units, and 240V workshop machinery.
• Like all premium QO breakers, the QO230 features the patented Visi-Trip indicator. When the breaker trips due to a short circuit or overload, a highly visible red flag appears in the window. This allows you to identify a fault at a glance without having to test the handle tension, which is especially helpful in poorly lit basements or mechanical rooms.
• This breaker is engineered exclusively for Square D QO "Blue Label" load centers, NQ panelboards, and switchboards. It uses a 1.5-inch wide (two 3/4-inch spaces) plug-on design. Note: It is not compatible with Square D Homeline, Eaton, Siemens, or GE panels. Always verify your panel type to ensure a safe, high-integrity electrical connection.
• The QO230 is built with an internal common-trip mechanism. If a fault occurs on either of the two poles, both poles trip at exactly the same time. This prevents "single-phasing" a dangerous condition where a 240V motor continues to run on only one leg of power, which can lead to overheating, motor burnout, or electrical fires.
• The Square D QO230 is UL Listed and CSA Certified with a 10,000 AIR (Amperes Interrupting Rating). It features high-quality pressure plate terminals that provide a secure, gas-tight connection for copper or aluminum conductors (#14 to #8 AWG), ensuring long-term reliability and full NEC/CEC compliance for your electrical infrastructure.
