The Deligo DSY3 Y3 Solar Branch Connector Set is designed for creating secure branch connections within solar PV installations, allowing multiple photovoltaic connections to be brought together as part of a solar DC wiring system.
Designed for 4mm solar connector systems, the DSY3 is rated at 30A and 1000V DC, making it suitable for professional residential and commercial photovoltaic installations.
With durable tin-plated copper alloy contacts, a secure snap-in locking system and IP67 protection when connected, the Deligo DSY3 provides a reliable solution for exposed rooftop and outdoor solar PV applications.
Y3 Solar Branch Connector Set
The DSY3 forms part of Deligo's range of Y-branch solar connectors and is designed for use where multiple solar PV connections need to be combined within the DC side of an installation.
Its Y3 configuration provides a practical solution for photovoltaic arrays where additional branch connections are required, helping installers keep solar cabling organised and securely connected.
4mm Solar Connector System
The Deligo DSY3 uses a 4mm connector system, making it suitable for use within compatible photovoltaic DC wiring installations.
Installers should always check connector compatibility with the existing solar PV system before making any connection.
30A 1000V DC Rating
The DSY3 is rated at 30A with a maximum rated voltage of 1000V DC under IEC specifications.
It also has a specified test voltage of 6kV at 50Hz for one minute, providing a robust connection for demanding solar PV environments.
Wide Operating Temperature Range
The connector is designed for use across a wide range of environmental conditions, with an IEC ambient operating temperature range of -40°C to +90°C.
The manufacturer's specification also lists an upper limiting temperature of +105°C under IEC conditions.
IP67 Protection When Connected
When correctly connected, the Deligo DSY3 has an IP67 ingress protection rating, helping protect the electrical connection from dust and temporary water immersion.
This makes it suitable for outdoor solar PV installations where connectors may be exposed to changing weather conditions.
Secure Snap-In Locking System
A snap-in locking mechanism helps provide a secure mechanical connection between compatible solar connectors, reducing the risk of accidental separation once correctly installed.
Durable Solar PV Construction
The electrical contacts are manufactured from tin-plated copper alloy, providing good electrical conductivity together with protection against corrosion.
The connector housing uses PC/PA insulation material and is rated to UL-94-V0 flame classification, making the DSY3 suitable for professional photovoltaic installations.
