HAGER SPA931 prepäťová ochrana SPD T1+T2 B+C 4P 4M 12.5/50kA 1.5kV TN-S

The HAGER SPA931 is a high-performance surge protective device (SPD) designed to protect electrical installations against transient overvoltages. Combining Type 1 and Type 2 protection (Class B+C), it is suitable for main distribution boards in TN-S systems. With a maximum discharge current of 50kA and a voltage protection level of 1.5kV, it ensures reliable protection for sensitive equipment.

Advantages

Combined Type 1+2 protection reduces installation space and cost. High surge capacity (12.5/50kA) handles direct lightning strikes and switching surges. Compact 4-module design fits standard DIN rail enclosures.

Suitable for

• Main distribution boards in TN-S earthing systems
• Commercial and industrial buildings requiring high surge protection
• Protection of sensitive electronic equipment against lightning and switching surges
