Stäubli MC4 Open-End Plastic Spanner Set PV-MS — Pack of 2 (32.6024)

Description

The Stäubli PV-MS Open-End Plastic Spanner Set (32.6024) is the official Stäubli assembly tool for MC4 solar connectors, supplied as a pair of two plastic open-end spanners. Used for tightening the cable gland on the rear of an MC4 connector and for releasing the locking mechanism to disconnect a mated pair safely. A matching pair of spanners is recommended for all MC4 assembly work.

⚡ Compatibility Notice — These spanners are designed for Stäubli original MC4 connectors only. They are not suitable for MC4-EVO2 connectors — use the dedicated metal spanner set PV-MS-PLS (32.6058) for EVO2. Tool colour may vary.

Frequently Asked Questions

What are these spanners used for?

The PV-MS spanners have two functions: tightening the cable gland on the rear of an MC4 connector during assembly (to achieve a correct IP-rated seal around the cable), and releasing the snap-lock between a mated male and female MC4 pair for safe disconnection. Using a matched pair of spanners — one on each connector — is the recommended method.

Will these work on MC4-EVO2 connectors?

No. The PV-MS (32.6024) is designed for original MC4 connectors only. For MC4-EVO2 connectors, Stäubli supplies the dedicated metal spanner set PV-MS-PLS (32.6058), and the separate unlocking tool PV-MS-MC4-EVO (32.6066) for EVO2 branch connectors.

Do I need two spanners?

Yes — when disconnecting a mated MC4 pair, one spanner engages the male connector and one the female, allowing you to twist the locking collar safely without damaging the housing. This set contains both spanners needed, so one pack is sufficient for a complete installation kit.
