FUSE SWITCH-DISCONNECTORS FOR CYLINDRICAL FUSE ...

Fuse switch-disconnectors and disconnectors for cylindrical fuse-links
FUSE SWITCH-DISCONNECTORS FOR CYLINDRICAL FUSE-LINKS SIZE 14x51
Fuse switch-disconnectors OPV14 are intended for cylindrical
fuse-links PV14 size 14x51. They can safely switch off rated
current and overcurrent up to 1.5 rated current and meet the
requirements for safe disconnection. Inverse connection is
permissible and it affects neither the technical parameters nor
the safety of the operator.
Switch-disconnectors OPV can be sealed in the closed
state.
The devices are designed as modular
for 45 mm cutout in the switchboard.
Optional light indication of fuse status.
Mounted on 35 mm „U“ rail according to EN 60715
or on the panel (steel rail recommended).
