ESE MOV Metal Oxide Varistor 33kv Building Types Of Lightning Arrester
types of lightning arrester Description
SPD (Surge Protective Device or called surge arrester) is an
appliance designed to protect electrical devices from voltage
spikes. A surge protector attempts to regulate the voltage supplied
to an electric device by either blocking or by shorting to ground
voltages above a safe threshold. We have spark gap, MOV and Spark
tube type for different protection area.
For the whole building lighting protection, 30kA-60kA, 40kA-80kA,
50-100kA, are available, however, 30kA-60kA is the most common one.
As we know, one building have two unita, one is A, the other one is
B, for A or B, surge arrester 20/40kA will be your best selection.
What's more, we also can provide the one such as surge arrester
5-10kA,especially 10-20kA to strongly protect the single room,
5-10kA to protect a single unit electric device.
types of lightning arrester Features
A high discharge capacity, low protection level and dual safety
Thermo Dynamic Control disconnector define the high reliability of
the devices.
types of lightning arrester Applications
- High discharge capacity thanks to powerful zinc oxide varistors
- Quick response
- Reliable control thanks to Thermo Dynamic Control disconnector
with dual monitoring
- Fault indication via red mark in the inspection window
- Slim design (modular construction) according to DIN 43880
- Multifunctional terminals for connection of conductors and
busbars
- Complete unit consisting of upper part and base, pre-mounted and
ready for connection
- Plug-in arrester with dynamic separating device
- With visual function display
- Enclosed, non-extinguishing zinc varistor arrester for use in
normal commercial distributor housings
Application example: building with an overhead power line supply or
lightning protection system, for building up lightning protection
equipotential bonding.
Apart from the standard visual indication with green and red
coloured marks, the variants of Greegoo.. BY series provide a
3-pole terminal for remote signalling. As the remote signalling
contact works as a floating changeover contact, the remote signal
can be used as a break or make contact, according to circuit
concept.
