Introducing the QO and QOB series, a range of high-performance thermal magnetic circuit breakers designed to deliver reliable overcurrent protection and efficient switching for AC systems. Engineered with precision and innovation, these circuit breakers offer a comprehensive solution for safeguarding electrical circuits.
At the heart of the QO and QOB circuit breakers is an advanced over center, trip-free toggle mechanism that guarantees exceptional performance. This mechanism ensures a quick make, quick break action for seamless operation, paired with an intuitive positive handle indication, making circuit management straightforward and user-friendly. The addition of the VisiTrip trip indication feature offers a visual cue, instantly signaling when the circuit breaker has tripped, promptly addressing interruptions in the circuit flow.
This specific configuration is a 1-pole QO circuit breaker, engineered to handle a current rating of 15A at both 120V and 240VAC. The circuit breaker is meticulously designed to provide a formidable 10kA breaking capacity, ensuring the ability to swiftly interrupt excessive currents, thus enhancing overall system reliability. The QO circuit breaker's plug-in mounting design ensures a hassle-free installation process, streamlining setup and integration.
A wide array of features and factory-installed accessories further enhance the adaptability of the QO circuit breaker. From shunt trips to auxiliary switches and alarm switches, these optional additions enable users to customize their circuit protection solution to match specific operational requirements.
The QO circuit breaker series boasts extensive certifications, including UL Listing under UL File E84967 and CSA Certification under CSA Master Contract 153555. This recognition validates the circuit breaker's compliance with rigorous safety and performance standards, cementing its position as a trusted choice for circuit protection.
