• High mechanical stability for support applications and for use in regions with high seismic activity
• Extremely reliable pressure relief for use in areas requiring special protection
• Excellent pollution layer characteristics for use in coastal and desert regions or in areas with extreme air pollution
• All three surge arrester product families feature a superior sealing system that reliably prevents moisture ingress
• Decades of trouble-free service
• Manufactured using only environmentally compatible materials

3EP porcelain surge arresters are ideally suited for the reliable protection of:

- Transformers- Circuit breakers- Generators- Motors- Capacitors- Bushings- Switchgear

The cage, made of fiberglass-reinforced plastic (FRP) rods, provides a rigid, reinforced structure ensuring high mechanical strength. 

The excellent sealing system prevents moisture ingress and partial discharges. 

In the extremely rare event of an overload, the arc can escape directly through the directional pressure relief devices. Strong, high-quality porcelain prevents the ejection of internal parts. The Siemens porcelain design offers extremely safe overload performance. 

3EP porcelain surge arresters are ideal for areas with heavy seismic activity and extremely strong winds.
