This lightning arrester is designed according to the IEC standard. It is applied to any lightning protection grade of the 220v power distribution system.
Characteristics
(1) Modular design, good leak tightness
(2)Working indication, remote signal interface, deterioration indication
(3) It can be installed on 35mm electrical rail so the installation and wiring is convenient
(4) Applying temperature-controlling circuit breaking technology, overcurrent fuse, thermal circuit breaker, automaticly tripping when deteriorating
(3) Low residual voltage, fast response, high current capacity,long life span
(4) Various specifications, easy maintenance
Applicable scope
(1) Low-voltage power distribution board in building
(2) Power distribution board for every floor in building
(3) Power distribution cabinet and power distribution board outdoor
(4) Power distribution system which the connection model is (3+1)or (1+1)
(5) TT,TN power supply system
(6) The working condition must be water-proof, damp-proof, dust-proof and anti-corrosion
