❓How to Choose

Confirm the solar cable conductor size and connector-pin barrel, then select the marked 2.5, 4, or 6mm² jaw position. Match the terminal manufacturer’s crimp requirements before production work.

❓How to Use

  1. Strip the solar cable to the pin barrel length without cutting conductor strands.
  2. Select the jaw position matching 2.5, 4, or 6mm² cable.
  3. Align the pin and conductor in the die, then close the ratchet through a full cycle.
  4. Inspect and pull-test the crimp before assembling the connector housing.

❓Which wire sizes are supported?

The H3 jaw is marked for 2.5, 4, and 6mm² solar cable, corresponding to AWG 14, 12, and 10.

❓Can it crimp ordinary insulated terminals?

No. This jaw profile is designed for compatible solar connector pins. Use the correct terminal-specific die for other connector types.

❓How do I select the correct die position and ratchet pressure?

Match the cable size to the marked jaw position, begin with the factory ratchet setting, and verify the result with an inspection and pull test before adjusting pressure.
