Brand

Voltage Family

MCY - 1000V Y-type photovoltaic branch cable assembly
15MCY - 1500V Y-type photovoltaic branch cable assembly; this breakdown covers the six 201, 301 and 401 models

Branch Configuration

201 - Two branches and one common lead; standard 4mm², 30A
301 - Three branches and one common lead; standard 4mm², 30A
401 - Four branches and one common lead; standard 4mm² or 6mm², 30A; each reference is listed with MCY or 15MCY

Description

Branch layout and model ratings

MCY photovoltaic cable assemblies use molded branch junctions with connector leads. The 201, 301 and 401 models provide two, three and four branches respectively. The 2Y and 3Y layouts distribute two or three Y-junctions along a lead.
