Overcurrent circuit breaker series 15kA 3-pole FAZ-B63/3 278853

3-pole Overcurrent Circuit Breaker – Reliable Installation Protection

This three-pole circuit breaker from Eaton's FAZ series is a key element of any safe electrical installation. It provides effective protection for circuits against overload and short circuit, and its high breaking capacity guarantees reliable operation even in harsh conditions. The B characteristic makes it ideal for protecting lighting circuits, socket outlets and devices with low inrush current.

Characteristics and Application

The FAZ-B63/3 circuit breaker is designed to operate in AC networks with a voltage of 400V and a frequency of 50-60Hz. Its rated current is 63A, making it suitable for protecting circuits with a medium load. The three-pole design allows for complete disconnection of the phase, neutral and protective PE conductor. The breaking capacity at 15kA (according to IEC 60947-2) at 400V provides high resistance to the effects of short circuits. Mounting is on a DIN rail, which simplifies and speeds up installation.

Key Advantages and Product Features

• High breaking capacity: 15kA according to IEC 60947-2 standard guarantees the safety of the installation in the event of a short circuit.
• B characteristic: Provides a quick response to overloads and short circuits, protecting sensitive electronic devices. Also allows for trouble-free starting of devices with motors that generate momentary current surges.
• Universal mounting: The possibility of connecting wires from both the top and bottom facilitates installation in various switchboard configurations.
• Wide range of wire cross-sections: Support for solid and stranded wires with a cross-section from 1 to 25 mm² provides flexibility when selecting appropriate cables.
• Solid construction: Made of high-quality materials ensures durability and reliable operation for a long time.
• IP20 protection class: Protects against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard for devices mounted inside switchboards.
• Compliance with standards: Meets the requirements of IEC/EN 60947-2 and EN 60898 standards, which confirms its safety and quality.

Additionally, the circuit breaker has energy limitation class 3 and surge category III, making it suitable for use in demanding industrial and commercial environments. The ambient temperature in operating conditions ranges from -25°C to +75°C, which allows it to be operated in a wide temperature range.
