Overcurrent circuit breaker series 15kA 3-pole FAZ-C40/3 278877

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole circuit breaker from Eaton's FAZ-C40/3 series is a key element in protecting electrical installations in residential, commercial and industrial buildings. Designed to protect against the effects of overloads and short circuits, it ensures safe and stable operation of electrical circuits. A rated short-circuit breaking capacity of 15 kA (at 400V) guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Characteristics and application

The FAZ-C40/3 circuit breaker is characterized by a C characteristic, which means it is ideal for circuits with devices generating inrush currents during start-up – such as motors, transformers or heating devices. The C characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated current of 40A makes it suitable for protecting circuits with medium loads. A width of 3 modules makes it easy to install in electrical distribution boards.

• Versatile application: ideal for protecting lighting, socket outlets and circuits powering electrical appliances.

• Rail mounting: designed for mounting on a standard TS35mm rail, ensuring quick and easy installation.

• Solid construction: made of high-quality materials, guaranteeing long-lasting and reliable operation.

• Contact position indicator: the presence of an indicator (red/green) facilitates quick identification of the switch status – whether it is on or off.

Technical parameters and compliance with standards

The FAZ-C40/3 circuit breaker meets strict safety standards, including EN 60898 and IEC 60947-2. Its technical parameters have been selected to ensure optimal protection of the electrical installation: the rated voltage is 400 V AC, and the rated short-circuit breaking capacity (Icu) is 15 kA at 400 V AC and 15 kA at 230 V AC. The circuit breaker has energy limitation class 3 and surge category III. The degree of protection IP20 provides protection against contact with fingers and solid objects with a diameter of more than 12.5 mm. It is possible to connect solid and stranded wires with a cross-section from 1 mm² to 25 mm². The operating temperature range is from -25°C to +75°C, which allows the circuit breaker to be used in various environmental conditions.

Thanks to compliance with European and international standards, the FAZ-C40/3 circuit breaker guarantees safety and reliable operation. It also has a CE marking confirming its compliance with the requirements of the European Union.
