MAINS-PLUGTRAB - Device protection for the control cabinet
A reliable surge protection concept consists of:
- Matching protection devices for multiple level protection
- Products to suit the particular network type and
- Short conductor lengths for an ideal protection level.
MAINS-PLUGTRAB is the answer to device protection (type 3), uniting all these points. The device protection forms the third stage in a multiple stage concept for the power supply. While lightning current arresters (type 1) and surge arresters (type 2) are installed in the main and subdistributions, arresters for the power supply from the PLUGTRAB range are installed directly before the terminal equipment. For three or five-conductor networks (L, N, PE or L1, L2, L3, N, PE), we have just the right device for mounting on DIN rails. The arresters can be positioned conveniently directly before the power supply units, for example, and snapped on. The conductor lengths are very short, since the protection devices are simply wired in the through wiring. Adapter cables are not necessary.

Characteristics of the MAINS PLUGTRAB
The features at a glance
The top features of the PLUGTRAB arrester types for the power supply are
- Pluggable arresters for service-friendly insulation value measurement
- Funnction display on the device and as remote indication
- Installation on the DIN rail directly at the device to be protected
- Slim design and minimum space requirements
- High nominal current, up to 16 amps
- Complete function test with TRABTECH CHECKMASTER
Preferred areas of application
The use of PLUGTRAB PT for the power supply is particularly sensible in control and process engineering, in control cabinet engineering and in building technology, i.e. in harsh industrial fields in which surges can aoccur as a result of switching operations, mains influence due to inductive loads (motors, contactors) and lightning strikes to the structure of the building.
