ETI is introducing new series of plastic fuse base PFB D0.

Advantages of plastic fuse base PFB D0:

Compact housing design without additional covers – IP 20 protection class, faster assembling
All parts are made of firestop material (GW 960°C)
More grip area for screwing caps
Front print – product data visible after installation in the cabinet
LED indication when fuse link operates - working also in case of open circuit at minimal wire capacitance
Contact material Cu - lower temperature rise, very lower power dissipation
Double input terminal - availability of connecting wire and isolated Busbar
Modular design -availability of assembling multi-pole versions on construction site
Two position snapper - enables easy replacement
