Premium variant

• This switchgear provides power to dwellings with a three-phase power system. The basic element providing energy distribution in this system is the KDB-S36T switchgear. Surface-mounted version. The switchboard can contain up to thirty-six 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-T1T2 275/240 3P+N device is to be installed as the main overvoltage protection (e.g. from lightning). This is a varistor type surge arrester for classes T1 and T2.
• Concerning protection against electric shock, this version of the electrical system is divided into two sections, i.e. two residual-current circuit breakers are used. The main protection against electric shock is a three-phase circuit breaker KRD6-4/40/30-A which operation covers the residential rooms, kitchen and bedroom. This protection has a rated current of forty amperes (In=40A) and a creepage of thirty milliamperes (Id=30mA). Both parameters can be found in similar systems and the creepage protection complies with current building law standards concerning the electrical systems. The second circuit for protection against electric shock is the circuit intended for the bathroom, to which, in this version of the system, we pay particular attention (due to humid conditions) and therefore for the bathroom a very sensitive circuit breaker - KRD6-2/16/10 with a rated current of sixteen amperes (In=16A) and a creepage of ten milliamperes is provided. This value is too low in the context of residential room but is perfect concerning specific conditions in the bathroom.
• Protection of electrical outlet circuits in each of the kitchen, bedroom or residential rooms 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 nominal current of ten amperes (In=10A) KMB6-B10/1.
