KRF T1-25 Ⅰ级电源浪涌保护器
Characteristics
· Provides high protection thanks to its combination of high strength gas discharge (GDT) and a block of high-energy varistor (MOV), allowing high discharge power and a low residual voltage.
· Easily replaceable plug-in modules with locking system.
· Base and modules configured for secure mounting.
· Easy maintenance through local fault locator.
