Product details

The ABB FS403M-B25/0.03 is a highly advanced protective switch that serves both as a residual current circuit breaker (RCBO) and overcurrent protection. With a rated voltage of 400 V and a rated current of 20 A, this device is designed for use in various electrical applications. It provides reliable protection against overload and fault currents, making it an essential component of electrical safety. The type B tripping characteristic ensures that the switch responds quickly under overcurrent conditions, while the type A fault current provides additional protection against direct currents. The protective switch is suitable for use in AC/DC applications and meets the IP20 protection rating, which protects it from solid foreign objects with a diameter greater than 12.5 mm. With its compact dimensions, it is easy to install and integrate into various electrical systems.

  • Residual-current device with overcurrent protection (RCBO)
  • Type B tripping curve for quick response under overcurrent
  • Suitable for AC/DC applications
  • IP20 protection rating for additional protection against foreign objects.
