The number of electrical consumers in residential homes and commercial buildings has increased significantly in recent years.
The latest electrical devices often have quite different characteristics in terms of current consumption than earlier devices, due to frequency converters or switched-mode power supply units, for example.
All of this requires protection strategies for electrical installations.
This also includes appropriate residual current circuit breakers that will cut the current immediately and safely in the event of a fault.
Wiring errors, insulation faults, defective devices or faulty work on electrical systems can trigger dangerous residual currents – and cause accidents or electrical fires as a consequence.
Residual current protective devices (RCCBs) can prevent this from happening. They protect against dangerous shock currents when conductive objects that are under tension are touched, either directly or indirectly.
Residual current operated circuit breakers quickly and safely cut the power to the monitored circuit if a set differential current is exceeded.
For many areas of application, the installation of RCCBs with rated residual currents no greater than 30mA is mandatory in new buildings. For example, since 1984 in rooms with a bath or shower, and since 2007, additionally, for all socket-outlet circuits with a rated current of up to 20 A that are intended for use by non-professionals and otherwise for general use.
Siemens portfolio of residual current protective devices includes basic residual current operated circuit breakers (RCCBs) with no integrated overvoltage protection, combined RCBO with residual current detective and overvoltage protection in a single device, and, as an alternative, RC unit that can be fitted to miniature circuit breakers (MCBs).
All RCDs are available in different types and versions suited to detecting different types of residual current and different areas of application.
DBI Control regularly use the 5SV3214-0 RCCB in our panels to protect against any electricity accidents, equipment damage and fires.
These switch types have been specifically developed for applicationsin the residential and office building sector. they come equipped with additional safety features, are easier to install and can be retrofitted with additional functions at any times.
