Surge protector DS240S-130DC, 180Vdc, 50A, CE

Surge arrester specially developed for the protection of DC voltages and photovoltaic installations. It has varistors with thermal fuse and is DIN rail mounted. The surge arresters also include a thermal disconnector as standard, have exchange modules for quick replacement of damaged parts and local optical and remote fault indication (potential-free contact).

Features:

• Compact 2-pole type 2 surge arrester
• Safe disconnecting device
• Protection against transverse and longitudinal overvoltage
• Modular structure (base part and replaceable module)
• Only 18 mm wide, saves space in the cabinet
• Remote status indication as standard
• Complies with IEC 61643-1 and EN 61643-11 standards
