PV Connector Crimping Tool 2.5 / 4 / 6 mm² – UH-PT-CR01

Model UH-PT-CR01

UH-PT-CR01 is a manual ratchet PV connector crimping tool for 2.5, 4 and 6 mm² solar cable conductors. Three tool configurations are available for crimping compatible non-insulated photovoltaic connector contacts during cable preparation, connector assembly and field installation.

2.5 / 4 / 6 mm² refers to conductor cross-sectional area, not cable outside diameter. Match both the die cavity and connector contact to the conductor size, and never perform crimping on an energized circuit.

Overview

Product Overview

UH-PT-CR01 is a PV connector crimping tool platform designed around the three common solar cable conductor sizes of 2.5, 4 and 6 mm². Dedicated crimping cavities allow the installer to select the appropriate die position for the conductor and compatible connector contact.

Three manual ratchet configurations are available with different handle and head designs while sharing the same core 2.5 / 4 / 6 mm² application range. The ratchet mechanism supports a controlled crimping cycle and helps improve repeatability compared with uncontrolled general-purpose pliers.

2.5 / 4 / 6 mm² Crimping Range

Dedicated crimping positions cover 2.5, 4 and 6 mm² conductor cross-sections commonly used in photovoltaic cable and solar connector assemblies.

Ratchet Crimping Mechanism

A mechanical ratchet controls the crimping cycle and helps provide more consistent compression than conventional non-ratcheting hand pliers.

Dedicated Solar Connector Contact Crimping

Designed for compatible non-insulated PV connector contacts rather than general-purpose insulated terminals, ferrules or cable lugs.

Three Tool Configurations

Compact, long-handle and ergonomic ratchet configurations provide different handling characteristics while serving the same primary PV connector crimping application.

Size-Marked Crimping Cavities

The required crimping cavity is selected according to conductor cross-section, helping installers distinguish between 2.5, 4 and 6 mm² solar cable sizes during termination.

Manual Field Installation

No electrical or pneumatic power source is required, making UH-PT-CR01 suitable for connector preparation during rooftop, commercial and utility-scale PV installation.

Selection

Choose the Right PV Crimping Tool

All UH-PT-CR01 configurations cover 2.5, 4 and 6 mm² PV cable conductors. Select the tool configuration according to preferred handling, installation frequency and connector contact requirements, then use the crimping cavity corresponding to the actual conductor cross-section.

Applications

Where This Product Is Used

Solar PV Systems

Solar PV Systems

Protection, connectivity and distribution components for photovoltaic arrays, string circuits and related solar DC systems.

UH-PT-CR01 is intended for preparing crimped photovoltaic connector terminations during solar cable assembly, installation and maintenance. Select the correct crimping cavity according to conductor cross-section and verify that the connector contact is compatible with the selected tool before crimping.

Installation

Installation Guidance

1. Make sure the PV circuit is de-energized before preparing or crimping any connector termination.

2. Confirm the solar cable conductor cross-section and select the corresponding 2.5, 4 or 6 mm² crimping cavity.

3. Strip the cable insulation to the length specified for the connector contact being installed. Do not damage or remove conductor strands.

4. Position the compatible PV connector contact correctly in the selected crimping cavity.

5. Insert the stripped conductor fully into the contact barrel and verify that the conductor is correctly positioned before closing the tool.

6. Squeeze the handles through the complete ratchet cycle until the mechanism releases normally. Do not interrupt the crimping cycle unless the emergency release function must be used.

7. Remove the crimped contact and inspect the termination for correct conductor position, complete compression and visible damage.

8. Perform any pull-force or dimensional verification required by the connector manufacturer's assembly specification.

9. Assemble the crimped contact into the connector housing according to the applicable connector installation instructions.

10. Never use conductor size alone to assume compatibility with a particular connector. The contact geometry and required crimp profile must also match the tool.

Important Notes

2.5 / 4 / 6 mm² refers to conductor cross-sectional area, not cable outside diameter. Match both the die cavity and connector contact to the conductor size, and never perform crimping on an energized circuit.

FAQ

Frequently Asked Questions

What cable sizes can UH-PT-CR01 crimp?

UH-PT-CR01 is designed for 2.5, 4 and 6 mm² PV cable conductors, corresponding to three dedicated crimping positions in the tool.

What does “2546” mean on a solar crimping tool?

The model designation 2546 is widely used on PV crimping tools designed around 2.5, 4 and 6 mm² conductor sizes. It is a common product-model convention rather than an IEC or other standardized tool designation.

Is 2.5 / 4 / 6 mm² the cable diameter?

No. These values indicate the conductor cross-sectional area. They do not represent the outside diameter of the finished solar cable.
