Select the branch topology according to the number of photovoltaic inputs that need to be combined into one parallel connection. When multiple strings are paralleled, the common branch conductor and downstream equipment must be sized for the resulting combined current.

Applications
Where This Product Is Used
Solar PV Systems
Protection, connectivity and distribution components for photovoltaic arrays, string circuits and related solar DC systems.
UH-PC-YB01 is intended for photovoltaic systems requiring multiple module or string connections to be combined in parallel. The 2-to-1 version suits simple two-branch connections, while the 3-to-1 and 4-to-1 versions provide higher branch counts for larger PV array layouts. Final conductor and circuit current sizing should account for the combined current on the common branch.
Installation
Installation Guidance
1. Identify the number of photovoltaic inputs that need to be connected in parallel and select the 2-to-1, 3-to-1 or 4-to-1 UH-PC-YB01 configuration.
2. Confirm the polarity of every PV input before making any branch connections.
3. Isolate the photovoltaic circuit before mating or disconnecting the branch connector assembly.
4. Connect each PV input to the corresponding branch interface and ensure that every connector is fully inserted and locked.
5. Connect the common branch output to the downstream PV cable or equipment connection.
6. Verify that the common branch conductor and downstream circuit are suitable for the combined current of all connected PV inputs.
7. Check polarity, connector locking and cable routing before energizing the photovoltaic circuit. Do not connect or disconnect the branch assembly while under electrical load.

FAQ
Frequently Asked Questions
What branch configurations are available for UH-PC-YB01?
UH-PC-YB01 is available in 2-to-1, 3-to-1 and 4-to-1 configurations for combining multiple photovoltaic connections into a common parallel branch.
What is the difference between the three UH-PC-YB01 variants?
UH-PC-YB01-2T1 combines two PV inputs, UH-PC-YB01-3T1 combines three inputs, and UH-PC-YB01-4T1 combines four inputs into one common branch connection.
Can I use the 4-to-1 version as four separate products?
No. The 4-to-1 configuration is treated as one complete branch topology. The corresponding polarity arrangements belong to the same UH-PC-YB01-4T1 product configuration rather than separate models.
Does a Y-branch connector increase the circuit current?
Connecting PV strings in parallel can increase the current carried by the common branch. The downstream conductor, connector and protection equipment must therefore be selected for the combined current of the connected strings.
Is a Y-branch connector the same as an inline fuse connector?
No. A Y-branch connector combines multiple PV connections in parallel, while an inline fuse connector provides overcurrent protection. See UH-PC-MF01 – 1000V Inline Fuse Solar Connector for the fuse-protected product.
Can a blocking diode be used with parallel PV branches?
Where the PV system design requires reverse-current blocking, an inline diode may be incorporated into the relevant branch circuit. See UH-PC-MD01 – 1000V Solar Diode Connector for the UHCCY diode connector option.
