Hager Surge Protective Device 4P SPE440S Type 2 TNS Uc 275V In 20kA Imax 40kA

The Hager SPE440S is a high-performance Type 2 surge protective device (SPD) designed to protect electrical installations against transient overvoltages. With 4 poles and compatibility with TN-S earthing systems, it ensures reliable protection for sensitive equipment in residential, commercial, and industrial applications.

Advantages

Robust protection with a maximum discharge current of 40 kA and a voltage protection level below 1.3 kV. The pluggable module design allows for easy replacement without rewiring. Visual status indication (green/red flag) provides immediate operational status. Compact 4-module width saves space on DIN rail.

Suitable for

• Main distribution boards in TN-S systems
• Protection of sensitive electronic equipment
• Industrial and commercial electrical installations
