MC4 Solar Crimping Tool WS-2546B for 2.5-6mm²

Product Description

The MC4 Solar Crimping Tool WS-2546B for 2.5-6mm² is a professional tool designed to perform precise and repeatable crimps on MC4 photovoltaic connector terminals. Its ratchet system and terminal positioner ensure that each crimp is executed with the correct pressure and geometry, preventing false contacts and overheating during operation. With a crimping force equivalent to 1.2 tonnes and a compact format of 230 mm, it is perfect for installers seeking reliability, speed, and consistent finishes both in new installations and maintenance.

Main Features

• Capacity 2.5/4.0/6.0 mm² (14–10 AWG): covers the most common sizes in solar cable.
• Crimping pressure 1.2 t: firm crimping that ensures low contact resistance.
• Terminal positioner to center the MC4 pin/female and achieve uniform crimping.
• Interchangeable die set for maintenance or replacement when necessary.
• Length 230 mm and weight 0.55 kg: ideal balance between power and portability.
• Ergonomic design with efficient transmission levers that reduce manual effort.

Advantages or Benefits

• Obtain safe and durable solar connections thanks to geometrically stable crimping.
• Reduce installation times: the positioner prevents rework and ensures repeatability.
• Minimize electrical losses and overheating by achieving low metal-to-metal joint resistance.
• Greater versatility: covers the three most used sizes in photovoltaics (2.5/4/6 mm²) with a single tool.
• Low ownership cost: interchangeable dies and robust mechanism for long service life.

Purpose or Applications

Indicated for crimping pins and sleeves of MC4 connectors in residential, commercial, and industrial PV strings. Useful in prefabrication of solar jumpers, termination of photovoltaic fields, cable repairs, and O&M tasks where connection quality and electrical safety are required.

Technical Specifications

Compatibilities

Tool suitable for standard MC4 connector terminals and solar cables of 2.5/4/6 mm². Compatible with high-voltage MC4 connector pairs (e.g., WSPVCC-1500) and Y-type branches (e.g., WSPVY3 3-to-1), as well as with PV cable with typical outer diameter 4.5–8.5 mm. Always use original MC4 pins and bodies and the correct cable size to ensure tightness and contact resistance.

The MC4 Solar Crimping Tool WS-2546B for 2.5-6mm² is the safe choice for achieving industrial-quality connections in your solar projects: precision, durability, and productivity in a compact and reliable tool.
