EPEPRO LONQ‑40.F PV DC Isolator Switch, 2P 32A DC1200V/1500V Compact Solar Disconnect Switch DIN Rail Mount for Solar PV System

About this item

1. Compact DC Isolator for Solar PV Systems LONQ‑40.F is a compact 2‑pole DC isolator switch designed for photovoltaic systems up to DC1200V/1500V. It provides reliable DC isolation for PV modules, strings and inverters, supporting safe maintenance, shutdown and emergency disconnection in solar power systems.
2. DC1200V/1500V Wide Voltage Rating With DC1200V/1500V wide voltage compatibility, this switch is suitable for both traditional 1000V PV systems and modern 1500V large‑scale solar plants. 32A rated current meets the requirement of higher string current for improved system design flexibility.
3. Compact DIN Rail Design The LONQ‑40.F adopts a compact modular structure with 35mm DIN rail mounting, saving installation space in PV combiner boxes and solar system cabinets. Lightweight and easy to install, it is ideal for space‑sensitive residential and commercial PV applications.
4. High Mechanical Endurance Mechanical endurance up to 20,000 operations ensures long‑term reliability and stable performance under frequent switching. The clear ON/OFF rotary handle provides intuitive status indication and safe operation during PV system isolation.
5. Durable PA Housing High‑quality PA housing with UL94 V‑0 flame‑retardant performance, providing enhanced electrical insulation, heat resistance and durability. The switch is suitable for harsh outdoor and industrial PV environments.
6. Safe DC Switching Performance Double‑pole isolation, high impulse withstand voltage up to 8kV and compliance with IEC/EN 60947‑3 standard ensure safe DC switching and isolation. OEM & ODM services are available for customized branding and packaging requirements.
