Inside/Indoor Isolation switch
Overview
WTBK - 0.5 type low voltage fuse switch knife is suitable for outdoor distribution circuit of 500 v, 50 hz, as the low voltage side of transformer protection and overload protection, under certain conditions can meet no-load and rated current, no-load transformer lines.
The use of the environment:
The altitude does not exceed 2000 meters.
The ambient temperature is not higher than +40° C, not lower than -25 ° C.
The relative humidity of not more than 85% ( relative to the +25± 5 ° C)
No combustion and explosion dangerous. No violent vibration and impact, no serious corrosion of metallic and insulating material chemical sites.
Structural characteristics:
HR20 low-voltage fuse switch adopts three pole together base type assembly, every great clip type of dynamic and static contact by pillar insulated respectively fixed on the base
Ceramic knife moving contact head part consist of two rigid of part of the insulation of conductive parts to each other together, by the user to choose the appropriate fuse link between these two
Between conductive parts, switch and fuse role. Equipped with arc suppression between dynamic and static contact contact, and design to the main contact to contact, touch arc suppression
Head. Contact, prevent burning arc the main contact on moving contact head are ring tripping device, available insulation with hook in the ground operation over a long distance
Break-brake. With simple structure, reliable in performance. Easy to use, etc...
