Description
TM SKY LIMITED HR17 series Fused Disconnect Switches provide an upper and lower input/output structure with knife introduction and arc extinguishing device; and there are closed detection holes from time to time on the cover of the switches with built-in signaling switches and detection switches. It can be equipped with optional fuse monitor and can also be used as knife switch. The switch is beautifully modeled, novel and simple, and complies with IEC60947-3 standard.
ApplicationsTM SKY LIMITED HR17 series Fused Disconnect Switches application areas and occasions include:
Industrial power distribution and control:
a) Factory workshop power distribution cabinet/power cabinet: as the power switch and short circuit protection for electric motor, welding machine, traveling crane, machine tool, fan, water pump and other power equipment.
b) Control cabinets/boxes: Provide isolation and short-circuit protection for control circuits (e.g. power inputs of PLCs, inverters, servo drives, etc.).
c) Lighting distribution box: as the switching and protection of lighting circuits of larger capacity.
d) Capacitor Compensation Cabinet: Isolation switching and short-circuit protection for switching capacitors (attention should be paid to the selection of suitable fuses to withstand the switching inrush).
Building electrics:
a) Building floor distribution box / main distribution box: as a branch switch and protection for the distribution of power to various floors or areas.
b) Power distribution box: power switching and protection for elevators, pump rooms, air-conditioning plant rooms and other larger electrical equipment.
c) Emergency power distribution box: Used in critical emergency circuits that require isolation and protection.
equipment supporting:
a) Various types of mechanical equipment: integrated in the electrical control cabinets of machine tools, packaging machines, production lines and other equipment, as the main power switch of the equipment or the power switch of the main components.
b) transformer low-voltage side: used for small distribution transformers on the low-voltage side of the line to provide isolation and short-circuit protection.
c) Power switching device: Used as an isolation point in some manual or automatic power switching schemes.
