Economic variant

• This switchgear provides power to dwellings with a single-phase power system. The basic element providing energy distribution in this system is the switchgear. The enclosure is flush-mounted, the switchgear aesthetically matches the place of installation (wall). KDB-F12T switchgear enclosure is prepared for up to twelve single-module switches. This switchgear consists of the switching and protection components for the system and equipment, and above all its users, against fault conditions such as overloads, short circuits and creepage from the system (a creepage might result in electric shock).
• This version of the switchgear contains the main disconnecting equipment of the entire system - the KMI switch disconnector. With this device, the user can switch off the power supply to the entire system, e.g. in the event of modernisation works. Due to the KLI control light, there is a possibility to check whether the installation is live.
• The main device protecting the installation in case of creepage (protection against electric shock) is the KRD residual-current circuit breaker. This version of the switchgear uses a double-pole circuit breaker with a rated current of twenty-five amperes (In=25A) and a creepage of thirty milliamperes (Id=30mA). The parameters indicated can be found in similar systems and the creepage protection complies with current building law standards concerning the electrical systems.
• Protection of electrical outlet circuits is provided by two circuit breakers with specification B and with rated current equal sixteen amperes (In=16A). The use of two KMB6-B16/1 devices ensures the separation of the socket system into two sections: the residential premises and the bathroom. Separate protection of the lighting system, in each of the mentioned places, is carried out using an overcurrent circuit breaker with specification B and a rated current of ten amperes (In=10A) KMB6-B10/1.
• This version of the switchgear uses separate protection of socket circuits and oven circuits in the kitchen by means of the residual-current circuit breaker. KRO6-2/B16/30-A residual-current circuit breaker is a protection device with specification B and a rated current of sixteen amperes (In=16A).
  In case of a seepage (electric shock), the protection value is thirty milliamperes (Id=30mA)
