Auto Recloser
Permanent magnet mechanism+High reliability intelligent control system
OEM & ODM,Complete epuipment
Comply with IEC Standards
Auto recloser is composed of permanent magnet mechanism and high reliability intelligent control system. It used to medium-voltage overhead power grid; It can be breaking, closed, load current, overload current, short circuit current, also has 0-3 times automatic reclosing function
Normal service condition:
1. Altitude≤2000(optional≤4000);
2. Ambient temperature: -30℃ to 70℃(optional -40℃ to 70℃)
3. Ambient humidity:Maximum average humidity, 24 hour ≤95%,1 month ≤90%
4. Maximum water vapor pressure:24 hours ≤2.2kpa,1 month ≤1.8kpa
5. The ambient air has no obvious pollution of dust smoke, corrosive or combustible gases, steams or smog
Features
1. high reliability, high mechanical and electrical life
2. No maintenance
3. Small size, light weight, easy to install
4. Standard relay protection and quick automatic reclosing function
