EMITER Switchgear Attached AC Hermetic IP65 Surge Arrester Noark Type 2, 50A 3-Phase, RCD Type A 63A/300mA

The EMITER Switchgear Attached AC Hermetic IP65 Surge Arrester Noark Type 2 is a robust surge protective device designed for industrial and commercial applications. It combines Type 2 surge protection with an integrated RCD (Type A, 63A/300mA) and a 50A switchgear, all housed in a hermetically sealed IP65 enclosure for outdoor or harsh environments.

Advantages

This all-in-one unit simplifies installation by combining surge protection, residual current protection, and switchgear in a single enclosure. The IP65 rating ensures protection against dust and water jets, making it suitable for outdoor use. Hermetic sealing prevents moisture ingress, extending product life. The visual status indicator (green/red flag) allows quick inspection of protection status.

Suitable for

• Outdoor electrical panels and distribution boards
• Industrial facilities requiring Type 2 surge protection
• Commercial buildings with sensitive electronic equipment
• Applications needing RCD protection (Type A) for AC circuits
