OBO BETTERMANN ÜSM-20-230I1PE65 Surge Protection Module for LED Luminaires, 1-Phase, Type 2 SPD, IP65 5092433

Engineered for LED luminaires and street lighting, the OBO ÜSM-20-230I1PE65 is a single-phase surge protection module that safeguards sensitive lighting electronics from transient overvoltages. Its IP65-rated housing and integrated design make it a robust choice for outdoor and industrial applications where reliability is critical.

Highlights

• Type 2 surge arrester per EN 61643-11
• Nominal voltage 230 V AC, max continuous voltage 275 V AC
• Discharge current 5 kA (8/20 µs), max 10 kA
• Voltage protection level < 1.3 kV (L-PE)
• IP65 protection for demanding environments
• Compact integrated design for LED luminaires

In daily use

The module connects via flexible leads and mounts directly into the luminaire or on a surface. With a response time under 25 ns, it reacts instantly to surges, protecting the LED driver and extending luminaire life. External pre-fusing is required.
