Overcurrent circuit breaker series 10kA 3-pole FAZ-K63/3 278917

Reliable protection for electrical installations with FAZ-K63/3

This three-pole circuit breaker from Eaton's FAZ series is key to the safe and stable operation of your electrical installation. Designed for both home and professional use, it provides effective protection against overloads and short circuits. The rated switching capacity of 10kA (at 400V) guarantees a quick response in emergency situations, minimizing the risk of damage and fire.

The FAZ-K63/3 circuit breaker is distinguished by its versatility – thanks to its K characteristic, it handles impulse loads well, such as starting motors or devices with heating elements. This makes it ideal for protecting circuits powering various types of receivers. Installation is simple and intuitive, and the compact dimensions (3 module width) allow for efficient use of space in the distribution board.

Parameters and functionality for professionals and users

This circuit breaker has been designed with the needs of both installers and end-users in mind. The rated current of 63A allows you to protect circuits with higher power consumption. The ability to connect wires with a cross-section from 1 to 25 mm² provides flexibility when choosing the appropriate cables. Additionally, high resistance to atmospheric conditions (operating temperature from -25°C to 75°C) and IP20 protection rating guarantee reliable operation even in difficult environmental conditions.

The use of the K characteristic means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important when protecting devices that generate such impulses – e.g. electric motors or transformers. This avoids unnecessary tripping of the circuit during normal operation of these devices. The rated impulse withstand voltage Uimp of 4kV provides additional safety in the event of overvoltage.

Key features and benefits:

• High switching capacity (10kA): Fast and effective protection against the effects of short circuits and overvoltages.
• K characteristic: Ideal for protecting circuits powering devices generating surge currents.
• Wide range of wire cross-sections (1-25mm²): Flexibility when choosing cables tailored to the needs of the installation.
• Compact dimensions (3 modules): Saving space in the distribution board.
• Wide operating temperature range (-25°C to 75°C): Reliability in various environmental conditions.
• Complies with IEC 60947-2 standard: Guarantee of safety and quality confirmed by certificates.
• Rated voltage 400V: Versatility of application in various electrical installations.
• Energy limitation class 3: Provides adequate protection in the event of an electric arc.
