Overcurrent circuit breaker Icn=15000A / Icu=15kA 3P 80A HMC380

Electrical installation protection with Hager HMC380 circuit breaker

Hager HMC380 circuit breaker is a reliable protection for electrical installations, designed for both home and commercial use. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to equipment and fires. This three-pole circuit breaker with a rated current of 80A and characteristic C is a solid element of every safe installation.

Characteristics and application

The HMC380 circuit breaker with characteristic C allows for short-term exceeding of the rated current without unnecessary tripping. This is particularly important when connecting devices with electric motors or other receivers with high starting current – such as pumps or compressors. This avoids frequent false alarms and ensures uninterrupted power supply. The rated breaking capacity of up to 15kA (at 230V and 400V) guarantees safety even in the event of serious failures.

• Versatile application: ideal for protecting lighting circuits, socket circuits and electrical appliances.
• Flush-mounting: allows for aesthetic integration of the circuit breaker into the wall, maintaining a neat appearance of the installation.
• Expandability: compatible with additional Hager equipment, allowing it to be adapted to individual needs.
• Durable construction: made of high-quality materials, ensuring long-lasting and reliable operation.

Technical parameters and compliance with standards

The HMC380 circuit breaker meets stringent safety standards (EN 60898 and IEC 60947-2), confirming its high quality and reliability. Its compact dimensions (width 4.5 modules, depth 70 mm) make it easy to install even in tight switchboards. Designed to operate in a wide range of ambient temperatures (-25°C to +70°C) and with a pollution degree of 3, it will perform well in various environmental conditions. Designed for AC voltage of 415V and insulation voltage Ui at 500V. The rated impulse withstand voltage Uimp is as high as 6kV, providing additional safety during operation. The possibility of connecting wires with a cross-section from 1mm² to 70mm² (solid) or from 1mm² to 50mm² (stranded) provides flexibility during installation. The degree of protection IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm.
