Schneider Electric's QH315 is a miniaturized circuit breaker that is intended to safeguard electrical circuits. The device weighs 0.39 kilograms and is engineered to support a maximum line-rated current of 15 A. It can effectively operate at voltage levels of 120/240 V AC. Structurally, the QH315 contains three poles, enhancing its usability within multi-phase systems. The tripping mechanism employs thermal-magnetic technology to react promptly to overload situations, ensuring circuit integrity and protection.
Designed for robust performance, this circuit breaker comes with a substantial interrupting capacity of 65 kA, which protects circuitry from short circuits. Its construction allows it to withstand temperatures from –25 to 40 °C, expanding its operational scope.
Installation of the QH315 is straightforward due to its plug-in mounting mode paired with a pressure plate. It accommodates wire sizes ranging from AWG 14 to 8, compatible with both copper and aluminum conductors. This product is mechanically durable, capable of enduring standard MCB cycling demands. The continuous current rating stands at 100% for a standard miniature circuit breaker, ensuring efficient operation.
The tightening torque necessary during installation is approximately 4.6 N·m. Dimensionally, the circuit breaker measures 3 inches in height, 2.25 inches in width, and 2.91 inches in depth. Furthermore, it meets various certifications, including UL, CSA, and HACR, affirming its quality and performance standards for safe electrical distribution.
