Description

The Stäubli MC4-EVO2 Y-Splitter is a pre-assembled cable assembly for parallel or serial-parallel connection of PV modules without any additional tooling. Each Y-splitter brings two MC4-EVO2 legs together into a single output, using vulcanised connectors for a permanently weatherproof seal. Rated at 1500 V DC and 53 A, and certified by TÜV Rheinland. Available as a Female Y-Splitter (32.0334) — two female sockets to one male plug — or a Male Y-Splitter (32.0333) — two male plugs to one female socket.

⚠ Installer Safety — Never connect or disconnect under load. Isolate the PV array fully before handling. Installation must be carried out by a qualified electrician.

⚡ Compatibility — For use with genuine Stäubli MC4 and MC4-EVO2 connectors only. Do not mix with third-party MC4-style products — mismatched contacts risk arcing and fire. Use one female and one male Y-splitter together to form a complete parallel string pair.

Frequently Asked Questions

Which variant do I need — female (32.0334) or male (32.0333)?

The female Y-splitter (32.0334) has two female socket legs that combine into one male plug output — used on the positive string rail. The male Y-splitter (32.0333) has two male plug legs that combine into one female socket output — used on the negative string rail. For a complete parallel string, use one of each as a pair.

What is the difference between a Y-splitter and a branch connector?

A Y-splitter (32.0333 / 32.0334) is a pre-assembled cable assembly with 0.5 m leads — the connectors are vulcanised directly onto the cable, providing a permanent weatherproof seal with no crimping required. A branch connector (e.g. 32.0196 / 32.0197) is a compact moulded unit that clicks directly onto existing MC4 cable connectors without any cable tail. Use a Y-splitter where you need short flexible leads; use a branch connector where cables are already terminated.

Are these compatible with standard MC4 connectors?

Yes — the MC4-EVO2 Y-splitter connectors mate with genuine Stäubli MC4 and MC4-EVO2 cable connectors. Do not use with third-party MC4-style connectors from other manufacturers, as contact pin differences can create poor mating, arcing, or fire risk.
