Overcurrent circuit breaker, 6kA, C characteristic, 1-pole, 20A MCN120E

Safety and protection of electrical installations

The Hager MCN120E circuit breaker is a key element of every electrical installation, providing effective protection against the effects of overloads and short circuits. Its single-pole design and rated current of 20A make it an ideal solution for protecting circuits for various purposes, both in residential and commercial buildings. Characteristic C guarantees delayed tripping, which is particularly important for circuits with receivers generating high inrush currents, such as motors or transformers.

Functionality and technical parameters

This compact circuit breaker (1 module wide) is designed for mounting on a DIN rail, which facilitates its integration with the existing distribution board. The rated short-circuit breaking capacity of 6kA ensures reliable operation in emergency situations. The MCN120E circuit breaker is characterized by its versatility – it works with wires with a cross-section from 1 to 35 mm² (solid) and from 1 to 25 mm² (stranded). The use of screw terminals, including biconnect type lower terminals, facilitates and speeds up installation, allowing connection of both wires and busbars.

Construction features and additional information

The circuit breaker meets the requirements of IEC EN 60898-1 standard, which confirms its high quality and safety of use. It is adapted to work in a wide temperature range (from -25°C to 70°C) and has a degree of protection IP20. Additionally, the manufacturer Hager offers a wide selection of accessories, such as auxiliary contacts or additional release units, which allow you to adapt the functionality of the circuit breaker to individual needs. The I²t limitation class is 3. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 4kV. The circuit breaker also has touch protection IP2x for the terminals.
