HR6-250/3P

HR6-250/3P

Hr6 series fuse type disconnector (hereinafter referred to as switch). It is mainly used as power switches, isolation switches, emergency switches and circuit protection in distribution circuits and motor circuits of high short-circuit current with rated voltage of AC 380~660V (50/60Hz) and agreed heating current up to 800A, but generally it's not used for direct opening and closing of a single motor.
Scope of application

Hr6 series fuse type disconnector (hereinafter referred to as switch). It is mainly used as power switches, isolation switches, emergency switches and circuit protection in distribution circuits and motor circuits of high short-circuit current with rated voltage of AC 380~660V (50/60Hz) and agreed heating current up to 800A, but generally it's not used for direct opening and closing of a single motor.

The performance of this product complies with the stadards of IEC60947-3 and GB/T14048.3.

Model and meaning

Structural feature

The switch consists of base, cover, and arc extinguishing chamber, is completely made of arc resistant plastic and is a fully plastic structure. The fixed contact is directly installed on the base, making the arc extinguishing chamber easy to disassemble and assemble. The arc extinguishing chamber has two parts: an inner chamber and an outer chamber, and multiple metal arc extinguishing grids are used to increase the arc extinguishing ability and improve the contact life.

The NT type fuse link is installed inside the cover, which can rotate in a fan-shaped manner along the support, and has a large electrical isolation to meet the requirements of the disconnector. The cover can be easily removed from the base, making it easy to install and replace the fuse link part. There are two sets of installation holes on the base to meet the requirements for installation inside various switchgear cabinets and on panels. On both sides of the switch, auxiliary contacts can be installed as needed to send signals indicating the opening and closing status of the switch.
