Product Description

Application:

This product is a high-capacity, low-voltage surge protective device (SPD) designed for Type 1 (Class B) installation at the main power inlet of low-voltage distribution systems, located at the boundary between LPZ0 and LPZ1 zones. It protects sensitive electrical equipment against damage from direct lightning strikes and induced transient overvoltages.

Featured:

* Impulse current Iimp (10/350 μs): 30 kA

* Normal discharge current In (8/20 us): 30 kA

* Max. continuous operating voltage Uc: AC 385 V

* Selectable circuit protection modes: 2P / 3P / 4P / 3N+NPE

* Utilizes high-performance graphite or gas discharge tube (GDT) technology with superior follow-current interruption capability .
