EPEPRO LONQ‑40.X 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.X 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. X‑type basic version without auxiliary indicator function, cost‑effective for mass solar projects.
2. DC1200V/1500V Wide Voltage Rating With DC1200V/1500V wide voltage compatibility, this switch fits both traditional 1000V PV systems and modern 1500V large‑scale solar plants. 32A rated current meets higher string current requirements and improves system design flexibility. Non‑polarity design simplifies on‑site wiring work.
3. Compact DIN Rail Design LONQ‑40.X features compact modular construction with standard 35mm DIN rail mounting, saving installation space inside PV combiner boxes and solar cabinets. Light‑weight and quick‑to‑install, perfect for space‑limited residential and commercial PV projects.
4. High Mechanical Endurance Mechanical endurance reaches 20,000 operations to guarantee stable long‑term performance under frequent switching cycles. Clear rotary ON/OFF handle offers visible status indication for safe manual isolation during PV system service.
5. Durable PA Housing High‑performance PA housing with UL94 V‑0 flame‑retardant property delivers superior insulation, heat‑resistance and ageing resistance, adapting to harsh outdoor solar installation environments. IP66 protection grade for outdoor box installation.
6. Safe DC Switching Performance 2‑pole full isolation structure, 8kV high impulse withstand voltage, fully compliant with IEC/EN 60947‑3 standard for secure DC breaking and isolation. OEM & ODM custom branding and packaging services are available.
