Overcurrent circuit breaker series 15kA 3-pole FAZ-D32/3 278899

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole circuit breaker from the FAZ series is a key element of every safe electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both devices and the installation itself. Its design and parameters make it a suitable solution for both domestic and public buildings, as well as in industry.

Characteristics and application

The FAZ-D32/3 circuit breaker is characterized by a D tripping characteristic, which means it reacts with a slight delay to short-term current surges. This makes it ideal for circuits with devices with high inrush current, such as motors or transformers. The rated current of 32A allows for the protection of circuits with medium load. The high short-circuit breaking capacity (15kA at 400V) guarantees safety even in the event of serious failures.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical appliances.
• D characteristic: ensures resistance to momentary current surges during device start-up, minimizing the risk of unnecessary tripping.
• High breaking capacity: 15kA at 400V guarantees effective protection in the event of short circuits.
• Mounting on TS 35 rail: facilitates and speeds up installation in electrical switchboards.
• Protection class IP20: provides basic protection against accidental contact and ingress of solid objects.

Design and technical parameters

The circuit breaker is made of high-quality materials, which guarantees its durability and reliability. A width of 3 modules allows for efficient use of space in the switchboard. The cross-section of the connected wire from 1 to 25 mm² allows you to connect wires of different thicknesses, adapting to the specifics of the installation. The rated voltage of 400V and the impulse withstand voltage of 4kV ensure safe operation under typical operating conditions. Energy limitation class 3 indicates the ability to withstand high short-circuit energies without damage. Additionally, the possibility of mounting additional accessories allows you to expand the functionality of the circuit breaker according to individual needs.
