Overcurrent circuit breaker Icn=10000A / Icu=10kA 4P 80A HMF480

Reliable protection of electrical installations – 4P 80A circuit breaker

This four-pole circuit breaker from Hager is a key element of every safe and reliable electrical installation. Designed to protect circuits against the effects of overloads and short circuits, it provides effective protection for both installers and end users. The rated current of 80A makes it ideal for securing circuits with higher power consumption.

Characteristics and application

The circuit breaker with characteristic C reacts quickly to short circuits, but at the same time allows for short-term overloads, which is particularly important in the case of devices with electric motors or other receivers with high starting current. This avoids unnecessary tripping of the circuit when starting such devices. The rated breaking capacity of up to 10kA (at 230V and 400V) guarantees safety in the event of serious failures.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical devices in residential and commercial buildings.
• Flush mounting: allows for aesthetic and discreet placement of the circuit breaker in the wall.
• Width 6 modules: allows for efficient use of space in the distribution board.
• Expandability: compatible with additional Hager accessories, which increases the functionality of the system.

Parameters and construction

The circuit breaker is made of high-quality materials, which ensures its durability and reliability. Energy limitation class 3 and surge category III confirm its resistance to working conditions in demanding environments. Protection class IP20 protects against accidental contact, and a wide range of operating temperatures (-25°C to +70°C) allows its use in various climatic conditions. The cross-section of conductors from 1mm² to 70mm² (solid) and 1mm² to 50mm² (stranded) provides flexibility when connecting different types of conductors. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 6kV.
