Power Surge Protector
Product Details
Surge Proctect Device for Power Distribution System
1.Application:
Expensive electronic equipment is being increasingly used in all kinds of business, industry, government and enterprise anddomestic households. Electronic discharge, over voltage cause by switching or by lightning often cause these highly sensitiveunits to fail.
Electronic equipment is especially prone up to 1.5km way from lightning strikes due to the electromagnetic fields and cable-bome over voltages. However, effective protection is now available.
Over voltage protective devices for TN-S,TN-C,TN-C-S,TT and IT power systems and plants are subdivided into Classes A,B,Cand D depending on their application area, accordingly to DIN VDE 0675-6 (11.89). Compex offers over voltage protective devicesfor Classes B to D, witch cover the complete installation on the low volage side.
2.Feature:
Metal-oxide varistor Arresters still work after frequent operation
An arrester module can be changed with the mains voltage on
1-4 pole Pre-wired arrester blocks Simple installation via the marked terminals
Thermal isolating device with optical indication, permanent check of arrester serviceability
An extremely short response time, a low protection level and a high current diversion capacity combined with long life.
No follow-up current can be registered after the surge has decayed.
If the surge arrester is damaged by overloading, the integral isolating device breaks the connectionto the mains. This is signalled by a red fault indicator.
3.Mounting:
The surge arrestor can easily be installed in any distribution box or switchgear cabinet by snap-fitting to any commercial 35 mmtophat rail. The multi-pole arresters are connected together by an earthing bridge at the factory, so that there is only one earth (PE)connection to make on site.
