Overcurrent switch series 15kA 2-pole FAZ-C40/2 278764

Protection of installations and devices – a reliable overcurrent switch

This two-pole overcurrent switch from the FAZ series is a key element of every safe electrical installation. It provides effective protection of circuits against overload and short circuit, protecting both devices and the installation itself. The C characteristic allows it to react more slowly to short current surges, so it tolerates the starting of devices with a motor well, and yet will act quickly in the event of a prolonged overload.

The FAZ-C40/2 switch is designed for durability and reliability. Its compact design (only 2 module widths) makes it easy to install in distribution boards, and high-quality workmanship guarantees a long service life. The rated short-circuit breaking capacity of 15 kA (at 230 V and 400 V) ensures safety even in difficult working conditions.

Key features and applications

• High short-circuit breaking capacity: 15 kA at 230 V and 400 V – ensures effective protection in the event of serious failures.
• C characteristic: ideal for circuits with devices with high starting current, such as motors or transformers.
• Wide voltage range: rated voltage of 400 V, which makes it a universal solution for many applications.
• Wire cross-section: possibility to connect wires with a cross-section from 1 to 25 mm², both solid and stranded.
• Operating temperature: trouble-free operation in a wide range of ambient temperatures from -25°C to 75°C.
• Overvoltage category III: suitable for installation in residential and commercial buildings.
• Degree of protection IP20: protection against touching with fingers and solid objects larger than 12 mm – standard protection for devices mounted inside distribution boxes.
• Possibility of additional equipment: extending the functionality of the switch by mounting additional signaling or auxiliary modules.

The FAZ-C40/2 switch is used in electrical installations of residential, commercial and industrial buildings where reliable protection against overloads and short circuits is required. It will be perfect in lighting circuits, socket circuits and powering electrical devices with different power consumption. Energy limitation class 3 provides adequate protection in the event of an electric arc. Power losses of 7.5 W minimize energy losses in the installation.
