EV high-voltage connectors
Barrel connectors, multi-core plugs and manual service disconnects for electric-vehicle battery packs, chargers and test rigs. Every part is priced per piece EXW in US dollars, with its cable sizes, contact count and rating published on the product page.
8 mm and 9 mm barrel connectors
The 8 mm family covers 1-core, 2-core and 3-core plugs rated 1500 V / 250 A for 25, 35 and 50 mm² cable, with the 1-core version published at 2000 V. The 9 mm 2-core part carries the same 1500 V / 250 A rating in a larger barrel, and an aluminium-shell 8 mm 1-core variant sits at the top of the range.
ST5 multi-core plugs and sockets
For lower-current power and signal runs: 2-, 3-, 4-, 5- and 6-core plugs and panel sockets, 800 V on the 3-core part. Cable size is 2.5 mm² in stock, with 4.0 and 6.0 mm² quoted on request — the variant list names the cable size for each part, so the ordering code carries it.
Manual service disconnects
The MNS disconnect is quoted in eighteen variants: nine current ratings from 80 A to 400 A, each in a front-mount and a rear-mount version. The MSD mini covers one 350 A variant without a fuse. Neither listing publishes a voltage rating, so those pages flag it for confirmation instead of quoting a number.
Every model in this family, side by side
16 parts across 16 models, one row each. Sealing, contact count and electrical rating are exactly as published on the part page; a cell is blank where the listing does not state the figure. Prices are USD per piece, EXW Yueqing, lead time 10–20 days.
