Hager Surge Protection Module N-PE Type 2 SPD 255V 20kA/40kA 1.5kV SPE040N

The Hager SPE040N is a plug-in surge protection module for the N-PE path, offering a high discharge capacity of 20 kA nominal and 40 kA maximum. Unlike many similar modules, it combines a low voltage protection level of 1.5 kV with a fast response time under 25 ns, ensuring sensitive equipment is shielded from indirect lightning and switching overvoltages.

Highlights

• Type 2 surge protection module for N-PE (neutral-earth) path
• Maximum continuous operating voltage 255 V AC
• Nominal discharge current 20 kA, maximum 40 kA (8/20 µs)
• Voltage protection level ≤ 1.5 kV
• Visual status indicator: green OK, red replace
• Plug-in design for easy replacement without rewiring

In daily use

Installed in a suitable DIN rail base unit, the SPE040N protects low-voltage installations in TN-S, TN-C-S, and TT systems. Its replaceable module design simplifies maintenance, and the clear status indicator allows quick checks. The thermoplastic housing in grey blends into standard distribution boards.
