DLSF8A24V, DLSF16A24V, DLSF20A24V, DLSF8A230V, DLSF16A230V, DLSF20A230V, thiết bị cắt lọc sét nguồn điện 1 pha LPI
LPI® DLSF Surge Filters
Features
3-Stage protection ensures lowest let-through voltage to protected equipment
Suitable for single phase TT, TN-S and TN-C-S distribution systems
Impulse discharge current rating of 25kA + 25kA 8/20μs Ph-N
Provides protection in all modes: L1-L2, L1-GND, L2-GND.
Designed to withstand fault and over-voltage conditions as per IEC61643
Non-saturating inductors – dv/dt of the incoming surge reduced by up to 100
times
Internal thermal fusing of protection elements ensures safe end-of-life operation
Power and Status indication with voltage free alarm contacts
5 Year Warranty
