The total current through the common connection must remain within the 30A connector and downstream circuit ratings.

UH-PC-TB01 is a rigid T-branch solar connector designed to combine multiple photovoltaic connections through one compact branch assembly. Five configurations are available from 2-to-1 through 6-to-1, allowing the branch count to be selected according to the required parallel PV wiring layout.

Unlike the cable-based UH-PC-YB01 – Y-Branch Solar Connector, UH-PC-TB01 integrates the branch paths directly inside a rigid PC housing using a brass conductor structure. The connector series is rated at 1000V DC and 30A, with IP67 protection when matching interfaces are correctly and fully mated.

Rigid Branch Housing

Five Branch Configurations

UH-PC-TB01 is available in 2-to-1, 3-to-1, 4-to-1, 5-to-1 and 6-to-1 layouts for different photovoltaic parallel-connection requirements.

Rigid T-Branch Structure

The branch interfaces are integrated into one rigid connector body rather than connected through separate cable leads.

Brass Internal Conductor

An internal brass conductor provides the electrical path between the common interface and the individual branch connections.

30A / 1000V DC Rating

The connector platform is configured for 1000V DC photovoltaic applications with a 30A rated current.

IP67 Mated Protection

Correct and complete mating provides IP67 environmental protection for applicable outdoor photovoltaic wiring.

Compact Parallel Connection

The integrated connector body reduces loose branch cable sections where a compact multi-port parallel connection is preferred.

Selection

Choose the Correct UH-PC-TB01 Branch Configuration

Select the T-branch version according to the number of photovoltaic connections that need to share one common interface. The 30A product rating applies to the connector assembly; when PV sources are connected in parallel, the total current through the common side must remain within the applicable connector, cable and downstream equipment ratings.

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-TB01 is intended for photovoltaic systems requiring compact parallel connections between multiple module or string interfaces. Its rigid 2-to-1 through 6-to-1 configurations are suitable where a centralized connector body is preferred over cable-split branch assemblies. The common connection and downstream PV circuit must be selected for the total current resulting from all active parallel branches.

Installation

Installation Guidance

1. Select the UH-PC-TB01 configuration according to the number of photovoltaic branch connections required: 2-to-1, 3-to-1, 4-to-1, 5-to-1 or 6-to-1.

2. Confirm the polarity of the common interface and every photovoltaic branch before making any connection.

3. Isolate the photovoltaic circuit before connecting or disconnecting the T-branch assembly.

4. Mate each photovoltaic branch connector completely with the corresponding UH-PC-TB01 interface and verify that the locking structures are fully engaged.

5. Connect the common interface according to the photovoltaic system wiring diagram.

6. Calculate the combined current of all active parallel branches and verify that the total current remains within the ratings of the UH-PC-TB01 connector, common-side cable and downstream equipment.

7. Do not leave unused energized branch interfaces exposed. Use the appropriate system design or protective measures for unused connections.

8. Check polarity, connector locking and complete mating before energizing the photovoltaic circuit. Do not connect or disconnect the branch connector under electrical load.

FAQ

Frequently Asked Questions

What T-branch configurations are available?

UH-PC-TB01 is available in 2-to-1, 3-to-1, 4-to-1, 5-to-1 and 6-to-1 configurations.

What is the rated current of UH-PC-TB01?

UH-PC-TB01 is specified at 30A. When multiple photovoltaic sources are connected in parallel, the combined current through the common interface must remain within the connector and downstream circuit ratings.

What is the difference between a T-branch and Y-branch solar connector?

UH-PC-TB01 uses a rigid integrated T-branch housing. UH-PC-YB01 – Y-Branch Solar Connector uses flexible cable leads between the branch interfaces, allowing more freedom in cable routing.

What is the difference between UH-PC-TB01 and UH-PC-YB02?

UH-PC-YB02 – Multi-Output Solar Branch Connector uses a centralized junction housing with factory-assembled cable leads. UH-PC-TB01 integrates the branch paths directly into a rigid multi-port connector body.

Can unused branch ports be left open?

Unused connector interfaces should not be left exposed in an energized outdoor installation. The system should be configured so that unused interfaces are safely isolated or protected against environmental exposure and accidental contact.

Does the branch connector provide fuse protection?

No. UH-PC-TB01 provides a parallel electrical connection and does not replace photovoltaic overcurrent protection. Where inline fuse protection is required, see UH-PC-MF01 – 1000V Inline Fuse Solar Connector.
