Surge protection devices
For the protection of low voltage equipment against transient voltage and current surges mainly from atmospheric origin (lightning) and transient produced by switching characteristics such as in switching of distribution networks, transformers, motors, etc.
Features:
- Comply with the IEC 61643-11
- Replaceable plug-in protection modules with visual fault indication
- Type 1+2 combined lightning and surge protection (in a single unit)
- Clamps voltage to less than 1500V as per SANS 10142-1:2008 table L1
- Prewired spark-gap-based type 1 and 2 combined lightning current and surge arrester
