HR17B Series Square Panel Mount Fuse Holder Disconnector Switch
Fuse Links Selection Guide:
The purpose of using fuses is to out off the line safely and
correctly to protect discrete components or the whole line in case
of circuit errors. The following are the necessary conditions to be
considered when selecting fuses.
Malfunction:
Malfunction is usually a result of incomplete analysis on the
design of circuit, Special attention should be given to 1) normal
rated current; 3) Ambient temper- ature; and 6)overload
increasement of factors to be considered for selection of fuses
listed below. For example, frequent reasons for malfunction under
normal working conditions are insufficient consideration to the
start current of capacitor circuit and the ambient temperature
around the fuse link.
HR17B series fuse-type disconnector Switches:
HR17B series fuse-type disconnector with load operation, suitable
for rated current 40A~1600A, there are 1 group, 2 groups, 3 groups,
4 groups of points. It can be mounted on the busbar, can also be
installed in the fixed plate; it provides the upper and lower input
and output structure, with a knife- edge introduction and
arc-control device; and the switch cover has irregular closed
detection holes, built-in signal switch, detection switch. it can
be optional fuse monitor, can also be used as knife switch. The
switch with beautiful shape, novel and concision, it meets the
lEC60947-3, GB140483 standards.

Factors To Be Considered For Selection of Fuses:
- Normal working current
- Working voltage
- Ambient temperature
- Overload current and cutout time
- Possible malfunction current
- Impulse current, surge current, starting current and transient value of the line
- Size and dimensions, connection methods, indicators, etc.
Ambient Temperature:
Ambient Temperature means the air Temperature directly around the
fuse, and should not be understood as the room temperature. In many
application cases, the fuses are at rather high temperature as they
are installed with supporting devices or bases in different
structures and they are closed in the distributing or controlling
boxes.
