2in 2out Solar Disconnet Switch with PV Cable LONQ-40.2-2

LONQ-40.2-2
Pre-Wired for Plug-and-Play Efficiency: Engineered by CNLONQ, this IP66 DC isolator comes factory-fitted with 4 professional PV1-F solar cables and MC4 connectors. Specifically designed for 2-in-2-out circuits, it offers the fastest installation time while ensuring a 100% secure, weather-tight connection

Ultimate 1200/1500V DC Protection: Built for high-efficiency solar arrays, this 4P PV disconnector supports extreme loads up to DC1500V 23A or DC1200V 32A. The non-polarity architecture allows for safe, bi-directional current flow, making it an essential safety hub for modern PV systems

IP66 Waterproof & Rugged PC/PBT Build: Featuring a high-impact UV-resistant PC enclosure and an internal PBT switch body, this unit is rated IP66 for total protection against heavy rain and dust. It maintains peak performance in extreme climates from -40°C to +85°C

Silver-Point Contacts for Superior Conductivity: The internal switch mechanism uses thickened copper conductors with silver-point contacts, ensuring low resistance and minimal heat generation. This professional-grade construction guarantees reliable power interruption over a long service life

Certified Safety & Integrity-First Mounting: Fully compliant with IEC60947-3 and certified by TUV, CE, UKCA, CB, RoHS, CCC and ISO. The enclosure includes external pre-drilled holes for rapid wall mounting, ensuring the waterproof seal remains intact throughout the installation process
