Specifications
Every value exactly as published in the official CUS101HEL documentation.
What ships 1
No. The holder and the link are separate parts. The link that goes in this holder is the Mersen HP10M20 — same 10 x 38 mm format, same 1000 V DC class — and we sell it alongside.
The price here is per piece, although Mersen packs them 12 to a box.
Installation 1
As many as fit, but derate. One to three poles side by side carry full current; from four upwards apply a factor of 0.9.
Temperature derates as well: full current to 40 °C, then 0.92 at 50 °C, 0.83 at 60 °C, 0.73 at 70 °C, 0.62 at 80 °C. A closed combiner box in summer sun reaches those numbers, so size on the inside temperature and not the shade air.
Configuration 2
Yes — CUS101IHEL (reference X1062758), same 32 A and 1000 V, with an indicator. It is packed 220 to a box rather than 12, so it only makes sense at volume. Ask and we will quote it.
No — 32 A is the holder's own thermal limit, the most it will carry with a link fitted. The protection rating is whatever link you put in it, which for a typical string is well under that.
Product information 2
Both. Used in both residential and commercial work. It is filed under one segment because the shop keeps one category per accessory; the part itself is not segment-specific.
Because we do not have one of this part, and we will not show you a different manufacturer's part in its place. Everything on this page is read from the manufacturer's own datasheet, which is linked above.
Ask us and we will send the manufacturer's product images with the quote.
