CHINT · HH15/QSA Fuse-Switch Disconnector, 63–1250A
Product overview
CHINT HH15/QSA is a manual fuse-switch disconnector. Select the rated-current frame and three- or four-pole base structure, then match the fuse and duty to the actual operating voltage.
Technical selection summary
| Current frames | 63,125,160,250,400,630,800,1000,1250A |
|---|---|
| Main poles in this selection | 3P or4P baseQSA |
| At AC400/415V | Use the corresponding frame current and the stated AC-23B/AC-22B duty |
| At AC690V | Operating currents by frame:63,100,160,250,315,425,500,500,500A respectively |
| Fuse requirements | RT16/RT20/NT orHDLRS3 according to frame and voltage; order the correct fuse separately |
| Protection distinction | Switch contacts do not create a standalone breaker Icu; the conditional short-circuit rating depends on the specified fuse |
| Other constructions | 3P+N and1/2 auxiliary-contact pairs require their exact ordering construction; not inferred from the base3P/4P code |
This selection covers the base3P/4PQSA structure. Frame current must not be applied unchanged at690V. Optional auxiliary contacts, neutral arrangements and fuse-included package suffixes need separate confirmation; no QP/QAS/QPS substitute is used.
