The WEICON Multi-Crimp MC4 is a professional ratcheting crimp tool designed for repeatable, process-safe electrical terminations. The ratchet mechanism includes a blocking device so the tool only opens after a completed crimp cycle, helping maintain consistent crimp quality. An emergency release is built into the handle for misuse situations, and eccentric adjustment allows fine tuning of crimp force. 

This set uses WEICON’s Multi Change System (tool-free module swapping) and includes 3 interchangeable module pairs:

• MC4 connectors (PV): 2.5 / 4 / 6 mm² (AWG 14–10)

• Insulated wire end ferrules: 0.25–6 mm² (AWG 24–10)

• Insulated cable lugs/terminals: 0.25–2.5 mm² (AWG 24–14)

Ergonomics & storage: Non-slip 2-component handles for comfortable force transfer; modules are stored in a compact plastic box/case.
