What is the Wago 792-803?
Short description:
Provides surge protection for IT systems and devices in the voltage range up to 60 V (except custom solutions, e.g., telephone systems with ringing voltage).
Overvoltage protection is also possible for DIN-35 rail-mount terminal blocks. Multi-stage surge arresters in rail-mount terminal blocks (792-80x Series) of just 6 mm width ensure cost-effective protection for control and bus technology (e.g., LON ® network, PROFIBUS network, binary signals).
Features:
Protect your system against overvoltage
Slim, space-saving design
Control operational costs by preventing expensive, unplanned downtime
High operational reliability and system uptime
Specifications
Notes
| Safety Information | - Installation must be performed by qualified personnel only.- The DIN-rail must be grounded.- The input current must be protected by a suitable fuse.- Protection against contact with stored charges must be ensured.- Do not insert or remove pluggable modules when energized.- The IP20 protection rating must be maintained in the assembled state or when using an end/intermediate plate compatible with the rail-mount terminal block. |
| Note | The coordination characteristics of the surge arrester provide information about its discharge capacity and protection capability. |
