Overcurrent circuit breaker series 15kA 3-pole FAZ-C50/3 278878

Electrical installation protection with FAZ-C50/3 circuit breaker

This three-pole circuit breaker with C characteristic is a reliable protection for your electrical installation. Designed to operate in AC networks with a voltage of 400V, it effectively protects circuits against overload and short circuit – just like any circuit breaker in this class. The rated current of 50A makes it suitable for securing circuits with medium loads.

The FAZ-C50/3 circuit breaker is distinguished by its high breaking capacity, reaching as much as 15 kA at 400V (according to IEC 60947-2 standard), which guarantees effective disconnection in the event of a serious failure. The C characteristic allows it to react more slowly to short current surges, so it tolerates the starting of devices with a motor or other loads generating high inrush currents.

• High breaking capacity: 15 kA at 400V ensures the safety of the installation even in the event of serious short circuits.
• C characteristic: ideal for circuits with loads generating surge currents, e.g. motors.
• 3 module width: compact dimensions make it easy to install in distribution boards.
• Wire cross-section 1-25 mm²: allows connection of wires of different thicknesses, adapting to the needs of the installation.
• Protection degree IP20: provides protection against accidental contact and ingress of solid objects.

The FAZ-C50/3 circuit breaker meets the requirements of EN 60898 standard (rated breaking capacity 10kA at 230V and 400V) and IEC 60947-2, which confirms its high quality and reliability. The ambient temperature in operating conditions ranges from -25°C to +75°C, allowing it to be used in various environmental conditions. Mounting is done on a TH35 rail, and the installation depth is 70.5 mm. The circuit breaker is designed to operate in networks with a frequency of 50-60 Hz and has a rated insulation voltage Ui of 440 V and a rated impulse withstand voltage Uimp of 4 kV.
