Overcurrent circuit breaker Icn=10000A / Icu=10kA 3P C 100A HMF390

Reliable protection of electrical installations – Hager HMF390 circuit breaker

This three-pole circuit breaker from Hager, with C characteristic and a rated current of 100A, is a key element of every safe and reliable electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. It is an ideal solution for both installers and end-users looking for solid and proven protection.

The HMF390 circuit breaker is designed to operate in AC installations with a rated voltage of 415V and a frequency of 50-60Hz. Its compact dimensions (width 4.5 modules, depth 70mm) allow for easy mounting in electrical distribution boards. The C characteristic provides delayed tripping during short-term overloads, which is particularly important for devices with electric motors or other loads generating high starting currents.

Solid construction and high resistance

The HMF390 circuit breaker is distinguished by its high quality of workmanship and durability. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is as high as 6kV, which guarantees safety even in difficult operating conditions. The IP20 degree of protection provides protection against accidental contact, and the wide operating temperature range (-25°C to +70°C) allows its use in various environments.

The rated short-circuit breaking capacity Icn is 10kA at 230V and 400V, which confirms its effectiveness in the event of serious failures. The possibility of flush mounting and compatibility with additional accessories (auxiliary contacts, overcurrent/undervoltage releases) increase its functionality and flexibility of use. Suitable for single-wire conductors with a cross-section of 1-70 mm² and multi-wire conductors 1-50 mm², it offers a wide range of possibilities for connecting different types of conductors.
