Overcurrent circuit breaker Icn=15000A / Icu=15kA 3P C 100A HMC390

Three-pole circuit breaker Hager HMC390 – reliable installation protection

The HMC390 circuit breaker is a key element of every safe electrical installation. Designed by the renowned Hager company, it provides effective protection against overloads and short circuits in circuits with a rated current of 100A. Its C characteristic makes it ideal for protecting circuits with receivers generating inrush currents, such as motors or transformers. This circuit breaker is used both in domestic and industrial installations where high reliability and safety are required.

Solid construction and high short-circuit breaking capacity

The HMC390 circuit breaker is characterized by high quality workmanship and durability. The rated short-circuit breaking capacity of 15kA (at 400V AC and 230V AC) guarantees effective disconnection of the circuit in the event of a serious failure, minimizing the risk of damage and fire. Energy limitation class 3 confirms its ability to cope with high short-circuit energies. Flush mounting and a width of 4.5 modules make it easy to integrate with existing switchboards.

Key features and benefits for installers and users

• C characteristic: Provides optimal protection for circuits with receivers with high starting current, such as motors or heating devices. Allows to avoid unnecessary tripping caused by short-term current surges.
• High short-circuit breaking capacity (15kA): Guarantees quick and effective disconnection of the circuit in case of a failure, protecting devices and installation from damage.
• Flush mounting: Enables aesthetic and discreet installation in walls or other structural elements of the building.
• Width 4.5 modules: Ensures compatibility with most standard electrical switchboards.
• Screw terminals: Allow for solid and reliable connection of wires with a cross-section from 1 mm² to 70 mm² (solid) and from 1 mm² to 50 mm² (stranded).
• Wide operating temperature range (-25°C to +70°C): Allows the circuit breaker to be used in various environmental conditions.
• Compliance with IEC 60898-1 and IEC 60947-2 standards: Confirms the safety and reliability of the device.
• Rated insulation voltage Ui: 500V: Ensures a high level of safety.

The HMC390 circuit breaker is an investment in safety and peace of mind – both for professionals involved in electrical installations and for end users. Its solid construction, high quality workmanship and compliance with applicable standards guarantee long-lasting and trouble-free operation.
