VII. Use and Maintenance
1. The switch shall be installed vertically, and the rated current of the
switch and the fuse shall be selected according to the capacity of the
electrical equipment.
2. The switch shall be equipped with RT0 filler cartridge fuse, and meet the
requirements of GB/T 13539.1 and GB/T 13539.2.
3. During the normal operation, the fuse indicator shall be checked
frequently to prevent the single-phase operation of the motor caused by
one-phase fuse. When there is a fault in multi-circuit power distribution
equipment, the fuse indicator shall be checked first, and the faulty circuit
shall be found out in time, and then the fuse shall be replaced to quickly
restore power supply.
4. When replacing the fuse, you shall disconnect the load circuit and wear
working gloves to avoid scalding your hands by the fuse pipe due to the
heat. After pressing the lock plate, the fuse can be easily replaced.
5. The contacts of the switch shall be checked regularly, and the dust, oil
and other impurities shall be cleaned up in time. The groove guide rail
of the switch must be kept clean to prevent ineffective operation due to
fouling.
6. No.3 sodium-based lubricant shall be coated on the contact surface of
the contact knife and socket when the fuse is self-equipped or replaced.
VIII. Ordering Information
When ordering, please specify the model and specification of the switch,
rated current of the fuse link and order quantity. If the rated current of the
fuse link is not specified, it shall be configured according to the conventional
thermal current of the switch. If the fuse link is self-equipped, a remark shall
be provided.
Examples of ordering: HR3-100/32, with 80 A fuse link, 10 sets
HR3-200/34, with self-equipped fuse link, 20 sets
