Operation
Siemens 3MT7 capacitor duty contactors
are specially designed to meet stringent
requirements of capacitor switching as
deliberated above. These contactors are
make auxiliary contact in series with quick
discharge damping six-resistors-2 per
phase to limit peak current to value within
contactor making capacity. The damping
resistors are activated via early make
auxiliary contacts before the main contacts
close. During switching, after attenuation
of the peak current, they are decoupled
again.
HRC Fuses
LV HRC fuse systems are used for installation systems in
non-residential, commercial and industrial buildings as well as
in switchboard assemblies of power utilities. They therefore
protect essential building parts and systems.
The components and auxiliary equipment are designed in
such a way as to ensure the safe replacement of LV HRC fuse
systems or isolation of systems.
LV HRC fuse links are available in the sizes 000, 00, 0, 1, 2, 3, 4
and 4a.
Benefits
LV HRC fuse links with combination front indicator the tripping
of a fuse. This enables identification and replacement of the
tripped fuse links. This increases system availability.
LV HRC fuse links are always equipped with silver-plated
contact pins. This means that they are non-corroding and have
less contact resistance. This ensures the long-term operational
safety of the plant.
