EMITER Switchgear Attached AC Hermetic IP65 Surge Arrester Emitter Noark Type 1+2, 20A 1-F

The EMITER Switchgear Attached AC Hermetic IP65 Surge Arrester is a robust Type 1+2 surge protective device (SPD) designed for industrial and commercial applications. It provides comprehensive protection against both direct lightning strikes (Type 1) and switching transients (Type 2) in AC power systems. With an IP65 rating, it is suitable for outdoor or harsh environments, ensuring reliable performance in demanding conditions.

Advantages

This surge arrester offers high surge current handling capacity (Iimp 12.5 kA, Imax 40 kA) and low voltage protection level (Up < 1.5 kV), ensuring sensitive equipment is safeguarded. The hermetic IP65 enclosure protects against dust and water ingress, making it ideal for outdoor installations. Visual status indication (green/red flag) allows for easy monitoring of operational status.

Suitable for

• Industrial power distribution panels
• Commercial building electrical systems
• Outdoor telecom and utility installations
• Renewable energy systems (solar, wind)
• Any AC system requiring Type 1+2 surge protection in harsh environments
