Overcurrent circuit breaker Icn=10000A / Icu=10kA 4P C 100A HMF490

Electrical installation protection with Hager HMF490 circuit breaker

This four-pole circuit breaker from Hager is a reliable protection for your electrical installation. Designed to protect circuits with a rated current of 100A, it guarantees safety and continuity of power supply. Its C characteristic makes it ideal for circuits with devices generating inrush currents, such as motors or transformers – allowing for short-term overloads without unnecessary tripping.

The HMF490 circuit breaker meets the highest safety standards, offering a rated short-circuit breaking capacity (Icn) of up to 10kA at 230V and 400V, as well as 10kA (Icu) according to IEC 60947-2. This is crucial for ensuring effective protection against the effects of short circuits and overloads. Energy limitation class 3 and surge category III further confirm its robustness and reliability in demanding conditions.

Installation and application

The HMF490 circuit breaker is designed for flush mounting, providing an aesthetic look of the installation. A width of 6 modules makes it easy to integrate with existing distribution boards. It accepts solid wire cross-sections from 1 to 70 mm² and stranded wires from 1 to 50 mm², providing great flexibility during installation. Designed to operate at temperatures from -25°C to 70°C, it will perform well in various environmental conditions. The possibility of expanding with additional equipment allows it to be adapted to specific installation needs.
