Overcurrent circuit breaker series 15kA 1-pole FAZ-B10/1 278531

Overcurrent circuit breaker – reliable protection for electrical installations

This single-pole circuit breaker from the FAZ-B10/1 series by Eaton is a key element ensuring safety in every electrical installation. Designed to protect circuits against overload and short circuit, it guarantees stable operation and long-term reliability. The rated switching capacity of 15kA (according to IEC/EN 60947-2) makes it an ideal choice for both domestic and professional applications.

Characteristics and application

The circuit breaker is characterized by a B characteristic, which means it reacts quickly to short circuits, but tolerates short-term current surges during the starting of devices with a motor (e.g. refrigerators, washing machines). The rated current of 10A makes it suitable for protecting circuits with medium power consumption. Mounting on a TH35 (DIN) rail is standard in most distribution boards, which facilitates installation and replacement. Thanks to its compact dimensions (1 module width) it allows for optimal use of space in the distribution cabinet.

• Overload protection: Protects the circuit against damage caused by excessive load.
• Short-circuit protection: Immediately disconnects the power supply in the event of a short circuit, minimizing the risk of fire and equipment damage.
• B characteristic: Ideal for circuits with devices with high inrush current.
• DIN rail mounting: Quick and easy mounting in standard distribution boards.
• Compact dimensions: Occupies only 1 module in the distribution cabinet.
• Rated switching capacity 15kA: High resistance to short-circuit currents ensures safety even in difficult conditions.

Construction and technical parameters

The FAZ-B10/1 circuit breaker is made of high-quality materials, which guarantees its durability and reliability. It has a protection class of IP20, which means protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV – this ensures safe operation in various installation conditions. The cross-section of the connectable single-wire or multi-wire conductor is from 1 to 25 mm², which allows connection of wires of different thicknesses. Additionally, the circuit breaker has energy limitation class 3 and surge category III – it meets safety standards.
