UH-PC-MC02 is a compact cable-to-cable solar connector designed for 1000V DC photovoltaic wiring. Three conductor-specific configurations are available: 30A for 2.5 mm² PV cable, 45A for 4 mm² cable and 50A for 6 mm² cable.

Compared with the UH-PC-MC01 platform, UH-PC-MC02 uses a different, shorter connector housing while retaining field crimp termination and IP67 protection when correctly assembled and mated. Tin-plated copper contacts are supplied as standard, with silver-plated copper contacts available on request.

Compact Connector Housing

The UH-PC-MC02 platform uses a shorter connector housing than UH-PC-MC01, providing an alternative form factor for PV cable installations where a more compact connector body is preferred.

Three Matched Cable Configurations

Available configurations pair the connector rating with the intended PV conductor size: 30A with 2.5 mm², 45A with 4 mm², and 50A with 6 mm² cable.

Crimp Contact Termination

Crimp termination provides a mechanical and electrical connection between the PV conductor and contact when the correct terminal and crimping die are used.

IP67 Mated Protection

The connector provides IP67 environmental protection after correct assembly and complete mating of matched connector components.

Standard Tin-Plated Contacts

Tin-plated copper contacts are supplied as the standard configuration for UH-PC-MC02.

Silver-Plated Contact Option

Silver-plated copper contacts are available on request for projects requiring an alternative contact surface.

Applications

Where This Product Is Used

Commercial Buildings

Protection, switching, distribution and enclosure components for commercial and light-industrial electrical installations.

Residential Electrical

Protection, switching and backup-power components for residential distribution boards and low-voltage electrical systems.

Solar PV Systems

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

UH-PC-MC02 is designed for detachable DC connections in PV module strings, solar extension leads and field-installed photovoltaic cable runs. Its compact connector housing provides an alternative form factor for residential, commercial and utility-scale PV wiring using 2.5, 4 or 6 mm² conductors.

Installation

Installation Guidance

1. Select the correct connector configuration for the installed conductor: 2.5 mm² / 30A, 4 mm² / 45A, or 6 mm² / 50A.

2. Prepare the PV cable without damaging the conductor strands or insulation required for sealing.

3. Insert the conductor into the correct crimp contact and complete the termination using a compatible crimping die.

4. Push the terminated contact into the connector housing until the contact is fully seated and retained.

5. Assemble and tighten the cable sealing section so that the seal grips the PV cable jacket correctly.

6. Mate both connector halves completely and confirm that the locking mechanism has engaged.

7. Check polarity, cable retention and complete mating before energizing the PV circuit.

PV Connector Wrench for Solar Connector Assembly – UH-PT-WR01

UH-PT-WR01 is a manual PV connector wrench platform available in 1000V flat-head, 1500V flat-head and 1000V round-head configurations. Each variant is designed for assembly and disassembly of compatible solar connector housings and cable-gland interfaces during PV installation and maintenance.

Important Notes

Rated current applies to the corresponding UH-PC-MC02 connector configuration and does not replace PV cable ampacity or system design calculations.

IP67 protection applies only after correct connector assembly and complete mating.

Use matched connector components from the same UH-PC-MC02 connector family. Similar geometry does not by itself confirm safe intermateability with connectors from another manufacturer.

Tin-plated copper contacts are supplied as standard. Silver-plated copper contacts are available on request.

Do not connect or disconnect photovoltaic connectors while the circuit is under electrical load.

Certification documentation depends on the selected production configuration and project requirements. Contact UHCCY for applicable documentation.

FAQ

Frequently Asked Questions

What cable sizes are available for UH-PC-MC02?

UH-PC-MC02 is available for 2.5 mm², 4 mm² and 6 mm² PV conductors, corresponding to 30A, 45A and 50A connector configurations.

What is the difference between UH-PC-MC01 and UH-PC-MC02?

Both are 1000V solar connector platforms for field-assembled PV cable connections. UH-PC-MC02 uses a different and more compact housing design, while the available conductor and current configurations are similar. Connector components from different product families should not be mixed unless compatibility has been specifically confirmed.

Are silver-plated contacts available?

Yes. UH-PC-MC02 is supplied with tin-plated copper contacts as standard, while silver-plated copper contacts are available on request.

Is UH-PC-MC02 suitable for outdoor PV installations?

The connector uses a PC insulated housing and is rated IP67 when correctly assembled and fully mated, making it suitable for applicable outdoor photovoltaic cable connections.

How should I select the connector current rating?

Select the version according to the specified conductor and PV circuit design: 30A with 2.5 mm², 45A with 4 mm², or 50A with 6 mm² cable.

What tools are needed to install UH-PC-MC02?

Installation normally requires PV cable preparation tools, the appropriate crimping tool and connector assembly tools matched to the selected conductor and contact.
