Overcurrent circuit breaker series 15kA 2-pole FAZ-C4/2 278752

Overcurrent circuit breaker – reliable protection for electrical installations

This two-pole circuit breaker from the FAZ series is a key element in protecting electrical installations, both in residential and industrial buildings. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to equipment and fires. Its compact size (2 module width) makes it easy to install in distribution boards.

Characteristics and application

The circuit breaker is characterized by a C characteristic, which means it reacts more slowly to short-term current surges. This makes it perfect for circuits with receivers generating surge currents during start-up, such as motors or transformers. The rated current of 4A makes it ideal for protecting lighting circuits, socket outlets or devices with lower power consumption. The breaking capacity of up to 15 kA at 400 V guarantees high effectiveness in the event of a short circuit.

• Versatile application: ideal for protecting lighting, sockets, household appliances and circuits with motors.

• C characteristic: ensures resistance to short-term current surges, protecting against unnecessary tripping.

• Compact dimensions: occupies only 2 modules in the distribution board, saving valuable space.

• High breaking capacity: 15 kA at 400 V provides effective protection in the event of a short circuit.

• Mounting on TH-35 rail: standard mounting simplifies installation and replacement.

Construction and technical parameters

The FAZ-C4/2 circuit breaker is made of high-quality materials, which guarantees its durability and reliability. It has a degree of protection of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The possibility of equipping with additional contacts allows expanding the functionality of the circuit breaker and adapting it to individual installation needs. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV. The cross-section of the connected wire can range from 1 to 25 mm², both solid and stranded – providing great flexibility during connections. The ambient temperature in operating conditions is in the range of -25°C to +75°C, which ensures its reliable operation even in difficult environmental conditions.

The circuit breaker has a rated current of 4A, a rated voltage of 400V and a time-current characteristic of C. The rated breaking capacity Icu is 15 kA at 400 V and Icn is 10 kA at 230 V / 400 V. The device occupies 2 modules width and has a degree of protection of IP20.

EATON circuit breakers meet strict safety standards and have a CE certificate, confirming their compliance with the requirements of the European Union. The manufacturer is Eaton Electric Sp. z o.o., providing high product quality and professional technical support.
