Overcurrent circuit breaker Icn=10000A / Icu=10kA 3P 80A HMF380

Overcurrent circuit breaker – reliable installation protection

This three-pole circuit breaker from Hager, with a rated current of 80A and C characteristic, is a key element of every safe electrical installation. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to equipment and fires. The rated short-circuit breaking capacity of 10kA (Icn) guarantees a quick response in emergency situations.

Design and application

The HMF380 circuit breaker is designed for mounting on a DIN rail in electrical distribution boards. Its compact dimensions (4.5 modules) allow for efficient use of space in the switchgear cabinet. The C characteristic means that the circuit breaker reacts with a slight delay to short-term current surges, which is particularly important when connecting devices with electric motors or other pulsed loads – this prevents unnecessary tripping under normal operating conditions. It is an ideal solution for both home and commercial installations.

Key features and benefits

• High short-circuit breaking capacity: 10kA ensures a quick and safe response in the event of a short circuit.
• C characteristic: Optimal for loads with inrush currents, such as motors or transformers.
• Modular mounting: Enables easy and quick installation on a DIN rail.
• Wide operating temperature range: From -25°C to 70°C guarantees reliable operation in various environmental conditions.
• Compliance with standards: Meets the requirements of EN 60898 and IEC 60947-2 standards, ensuring safety and reliability.
• Wire cross-section: Possibility of connecting solid wires with a cross-section of 1-70 mm² and stranded wires 1-50 mm², which provides great flexibility when selecting power cables.
• Protection degree IP20: Provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside distribution boards.
• Rated voltage 415V: Designed to operate in three-phase networks with a voltage of up to 415V AC.

The HMF380 circuit breaker is a solid and reliable solution for every installer and user looking for safe and effective protection of their electrical installation. Its high quality of workmanship and compliance with applicable standards guarantee long-lasting and trouble-free operation.
