EATON HN-C20/3 interruttore automatico modulare MCB, 20A, 3 poli, curva C, 6kA

The EATON HN-C20/3 is a high-quality miniature circuit breaker (MCB) from the HN series, designed for reliable overcurrent protection in residential, commercial, and industrial electrical installations. With a rated current of 20 A and a tripping characteristic C, it provides optimal protection for circuits with moderate inrush currents, such as lighting and motor loads. The 3-pole configuration ensures simultaneous disconnection of all phases, enhancing safety and system integrity.

Advantages

This MCB offers robust thermal-magnetic protection against overloads and short circuits, with a breaking capacity of 6 kA according to IEC/EN 60898-1. Its compact 3-module design (52.5 mm) saves space on DIN rail mountings. The screw terminals accommodate conductors up to 25 mm², ensuring secure connections. With IP20 terminal protection and IP40 front protection, it is suitable for use in distribution boards and enclosures.
