Overcurrent circuit breaker, 6kA, characteristic C, 3-pole, 20A MCN320E

Safety and reliability in your installation

The Hager MCN320E circuit breaker is a three-pole device designed to protect electrical circuits from the effects of overloads and short circuits. A rated current of 20A combined with characteristic C makes it an ideal solution for installations with receivers with increased inrush current, such as motors or transformers. It provides effective protection in both residential and public buildings.

Design and parameters

This circuit breaker is distinguished by its solid construction and high quality workmanship. Mounting is done on a standard DIN rail, which facilitates integration with existing modular equipment. The rated short-circuit breaking capacity Icn is 6kA, and Icu at 400V AC is 10kA – guaranteeing a quick response in emergency situations. The device has a protection degree of IP20, which provides basic protection against touch and dust. It is designed to operate at temperatures from -25°C to 70°C. The possibility of connecting wires with a cross-section from 1 to 35 mm² (solid) and from 1 to 25 mm² (stranded) ensures wide compatibility with various types of installations.

Functionality and benefits for professionals and users

The MCN320E circuit breaker offers a number of conveniences for both installers and end users. Screw terminals, including lower biconnect type terminals, facilitate and speed up installation, allowing simultaneous connection of wires and busbars. Characteristic C provides delayed tripping, which minimizes the risk of unnecessary circuit tripping when starting devices with high inrush current. In addition, high quality workmanship and compliance with IEC EN 60898-1 standards ensure long-lasting and trouble-free operation of the device. Three modules wide makes it easy to fit into a standard distribution board.
