QH320

The QH320 from Schneider Electric is classified as a miniature circuit breaker. With a line rated current of 20 Amperes, it is designed for operation within a voltage range of 120 to 240 Volts AC. This three-pole circuit breaker can interrupt fault currents of up to 65 kA, ensuring significant protection against electrical overloads. The breaking capacity of this unit is designated as G.

This circuit breaker operates utilizing thermal-magnetic trip technology, effectively responding to overcurrent conditions. A significant feature of the QH320 includes the VisiTrip trip indicator, which provides local signaling to inform users of trip events. It is constructed for plug-in mounting and employs a pressure plate mechanism for secure installation.

Within typical conditions, it can handle ambient temperatures of up to 40 °C, remaining robust and effective even in warmer environments. The continuous current rating allows for operation at 100% of its final current capacity. Additional specifications include a tightening torque of approximately 4.6 N·m. The circuit breaker has overall dimensions of 3 inches in height, 2.25 inches in width, and 2.91 inches in depth, ensuring it fits into standard electrical panels efficiently. Weighing just 0.39 kg, the QH320 is both lightweight and compact, fitting well in different installation environments.

This model is certified under UL, CSA, and HACR standards, indicating its compliance and suitability for use in general electrical applications.
