Product Description

Whon the arrester in thonormal working voltago, the ourrent flowing through the arrester onlymicroampere level, When sabjected to over voltsge, due to the nonlinear ZnO varistor, the current flowing through tho arroster Instant thonsands of amps, lightning arrester in the conduction state, the release ofover-yoltage energy, thus Effective to limit tho over-voltage on the transmission and distribution oquipment infringement.

Application & Characteristics

Metal oxide surge arresters for the protection ofAC electrical power systemequipmentfrom the atmosphere over-voltage and over-yoltage damage.

Condition of use

1. Ambienttemperature: -40 C-40C;
2. Elevation :1000-2000m(at high altitude should be ordered withregistration);
