DOCUMENTS

Document packs

Tell us the model and the document — the current revision is sent digitally. Nothing is published here that could go out of date without notice.

Product datasheets

PDF — electrical ratings, materials, cable range, temperature and IP rating for each model.

Dimension drawings

PDF — mounting, panel cut-out and thread dimensions for the selected model.

Certificates and test reports

PDF — CE certificates, REACH and RoHS (RSL-SCCP) reports for the lines that hold them.

Selection tables

XLSX / PDF — voltage and current matrix across connectors, terminal blocks and combiner boxes.

Installation guidance

PDF — crimping, torque, mating and sealing instructions for the connector series.

Combiner configuration sheet

PDF — string layout, fuse and breaker ratings, SPD selection and enclosure options.

REQUEST

How a document request works

One request, one current document. No registration and no gated download list.

01

Identify the model

Use the product page or the selection table to find the series and current class.

02

Tell us the document

Datasheet, drawing, certificate pack, installation guide or configuration sheet.

03

Receive the current revision

Sent digitally with its revision date. Older revisions are replaced, not archived on the site.

QUOTE INPUTS

What to send for a quote

Send these five and the reply comes back with a model, a drawing and a lead time — not a catalogue page.

01

System voltage and maximum current

The two figures that decide the series and the contact rating.

02

Cable size and conductor type

Cross-section and insulation diameter set the seal and crimp.

03

Interface to match

Existing connector half, terminal stud or panel cut-out.

04

Quantity per model

Order quantity and expected annual volume.

05

Destination and Incoterm

Port, warehouse or door delivery, and the terms you buy on.

GLOSSARY

Glossary

What does MC4-compatible mean?
The connector follows the MC4 mating and locking concept and is built to mate with connector halves that share the same interface dimensions. Compatibility must be verified per pair — similar appearance is not proof.
A series-connected group of PV modules. String current sets the fuse rating and the cable size, and the number of strings sets the combiner configuration.
It consolidates several DC strings into one output before the inverter, with per-string fusing, surge protection and a DC breaker for isolation.
Type 1 handles partial lightning current; Type 2 handles switching and induced overvoltage. The combiner boxes use a combined T1+T2 SPD.
IP65 is protected against dust and water jets; IP67 allows temporary immersion. The rating only applies to a correctly assembled and correctly mated connection.
The resistance across the mated contact pair. Lower values mean less heating at the joint; the connector series is specified at ≤0.5 mΩ.
