The Phoenix Contact 2817741 is a Type 2 surge arrester designed for DIN rail mounting. It provides protection against transient overvoltages in low-voltage power distribution systems. The device accommodates a nominal voltage of 500 V AC at 50/60 Hz and has an arrester rated voltage of 600 V AC. It features a short-circuit resistance of 25 kA with a maximum required backup fuse of 125 A (gL/gG). The module is a single-position, two-section divisible DIN rail module with a width of 17.7 mm, height 90 mm, and depth 52 mm. Connection is via biconnect screw terminal blocks with M5 screw threads and a tightening torque of 4.5 Nm. The housing is made of PA (polyamide) in black with IP20 degree of protection. The operating temperature range is -40°C to 80°C, and it complies with IEC 61643-1 and EN 61643-11/A11 standards. The arrester is suitable for applications requiring reliable overvoltage protection in industrial and commercial installations.
