Description
The connector consists of a plug part and a socket part. The metal contacts are crimped on the stripped conductor, inserted into the housing until the latch clicks, and the nut with the seal is tightened, so the connection stays sealed on an open roof. The plug and socket snap together and do not come apart by accident. The connectors SCF/C-1000V and SCF/C-1500V-A are rated for 2.5–6 mm² cables, and SCF/C-1500V-B for 10 mm². The branch connector SCF/D-2TL-1500V on a flexible hose joins two strings into one and has 1500 V insulation. The SCF/FUSE holder in an MC4 housing contains a sealed 20 A fuse that can be replaced with 15 or 20 A, so a separate chain of modules is protected without a fuse box. The contacts are crimped with SF-MC4 pliers, and an installation guide is included with the connectors. They are used in grid-connected and off-grid solar plants, energy storage systems and other DC installations.
How to choose
The connector is chosen by the cross-section of the photovoltaic cable and the maximum system voltage, 1000 or 1500 V. For a 10 mm² cable you need SCF/C-1500V-B, while for 2.5–6 mm² SCF/C-1000V and SCF/C-1500V-A are suitable. Parallel connection of strings is covered by SCF/D-2TL-1500V, and protection of a chain by the SCF/FUSE holder. Only compatible MC4-type products should be mated with each other.

FAQ
What cable cross-sections are the SCF/C connectors designed for?
SCF/C-1000V and SCF/C-1500V-A are rated for 2.5–6 mm², and SCF/C-1500V-B for 10 mm².
What fuse is fitted in the SCF/FUSE holder?
A built-in sealed 20 A fuse, which can be replaced with 15 or 20 A. The holder is made for 1000 and 1500 V.
What is used to crimp MC4 contacts?
A special crimping tool for MC4 is needed, for example SF-MC4 pliers. The contact is inserted into the housing until it clicks and the nut is tightened.
How are two strings connected in parallel?
The SCF/D-2TL-1500V branch connector joins two into one and has 1500 V insulation.
