2 or 1 in 2 or 2 out Solar Disconnet Switch Isolation LONQ-40.M20

LONQ-40.M20
Versatile DIY Wiring Configurations: Designed for ultimate flexibility, this CNLONQ DC isolator supports multiple wiring modes, including 1-in-1-out, 2-in-1-out, and 2-in-2-out configurations. Equipped with M20 cable glands, it allows solar installers to customize the connection based on specific PV string requirements

Industrial-Grade 1200/1500V Protection: Built for high-capacity solar arrays, this 4P switch-disconnector is rated for DC1500V 23A and DC1200V 32A. The non-polarity design ensures safe bi-directional current interruption, making it compatible with a wide range of DC systems

IP66 All-Weather Durability: The outer enclosure is crafted from high-impact UV-resistant PC, while the internal switch uses flame-retardant PBT. With an IP66 waterproof rating, it operates reliably in extreme temperatures from -40°C to +85°C, protecting internal components from torrential rain and dust

Premium Silver-Point Conductivity: To ensure long-term stability and minimal power loss, the internal conductors feature thickened copper with silver-point contacts. This professional-grade construction prevents overheating and ensures superior electrical performance over thousands of cycles

Certified Safety & Effortless Installation: Fully compliant with IEC60947-3 and certified by TUV, CE, UKCA, CB, RoHS, CCC and ISO. The box features external mounting holes, allowing for quick wall installation without drilling through the waterproof shell, preserving its airtight integrity
