What surge protector should I use for outdoor PoE devices?

For outdoor PoE links, the Axtren SG-48WP-Outdoor is an IP67 Gigabit Ethernet surge protector compliant up to PoE++ (IEEE 802.3af/at/bt). For indoor cabinets, the SG-48WP mounts on a 35 mm DIN rail. Both are tested to IEC 61643-21 with 10 kA total nominal discharge current.

What does the SG-48WP surge protector protect?

Gigabit Ethernet (1000 Mbit/s) and PoE links up to PoE++ (IEEE 802.3af/at/bt) on CAT 6 / Class E cabling up to 250 MHz.

How is the SG-48WP installed?

It mounts on a 35 mm DIN rail near the protected equipment, with shielded RJ45 input/output and a screw earthing terminal.

What standards does the SG-48WP meet?

IEC 61643-21, EN 61643-21 and GB/T 18802.21, with CE certification. Total nominal discharge current is 10 kA.
