Optimal variant

• This switchgear provides power to dwellings with a single-phase power system. The basic element providing energy distribution in this system is the KDB-S24T switchgear. Surface-mounted version. The switchboard can contain up to twenty-four 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.
• In this version of switchgear, the KSD-T2 275/40 device is to be installed as the main overvoltage protection (e.g. from lightning). This is a varistor type surge arrester for class T2.
• Concerning protection against electric shock, this version of the electrical system is divided into three sections: residential rooms, kitchen and bathroom. In each of these sections, 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 system 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. What is important, for the residential rooms it is a specification A device that detects the interference from electronic equipment such as computers, phones, etc. - KRD6-2/25/30-A. In the case of the other two sections, i.e. the kitchen and bathroom, they are AC residual-current circuit breakers KRD6-2/25/30.
• Protection of electrical outlet circuits in each of the sections is performed by overcurrent circuit breakers with specification B and rated current equal to sixteen amperes (In=16A) KMB6-B16/1. 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 dishwasher and oven circuits 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). Due to these parameters, the supply of very specific circuits for large appliances in the kitchen will not affect the supply to the rest of the rooms.
