Enclosed DC Switch IP67 Nema 4X 2 Pole 1 String 32A 700VDC Lockable Rotary Handle

Enclosed DC Switch IP67 Nema 4X 2 Pole 1 String 32A 700VDC Lockable Rotary Handle (SI32-PEL64R-2) Enclosed DC Switch – IP67 / NEMA 4X 2 Pole • 1 String • 32A • 700 VDC Model: SI32-PEL64R-2 The SI32-PEL64R-2 Enclosed DC Switch is a premium DC isolator designed for demanding photovoltaic (PV) system applications requiring reliable, safe DC disconnection at higher current levels. This model is rated at 32A with a maximum of 700 VDC, making it ideal for single-string solar circuits in residential, commercial, and industrial systems. Built with true DC switching technology (not simply AC-derated), the SI32-PEL64R-2 ensures controlled arc suppression under load, extended contact life, and consistent operational safety across thousands of switching cycles. Included in a rugged IP67 / NEMA 4X enclosure, this switch provides excellent protection against dust, water ingress, corrosion, and UV exposure — perfect for both indoor and outdoor installations including rooftop and exposed PV array environments. Key Features & Benefits 2-pole DC isolator for safe isolation of a single PV string Rated at 32A with 700 VDC maximum operating voltage Purpose-built true DC switching design for reliable arc control IP67 and NEMA 4X enclosure for harsh outdoor environments Lockable rotary handle to support lockout/tagout safety procedures Clear, positive ON/OFF position indication UV-resistant, corrosion-resistant enclosure materials Long mechanical and electrical service life Suitable for residential, commercial, and industrial PV systems Safety & Installation The lockable rotary handle allows the switch to be secured in the OFF position during maintenance or troubleshooting, significantly improving worker safety and reducing the risk of accidental energization. Clearly marked ON/OFF positions and ergonomic handle design facilitate fast inspection and acceptance by Authorities Having Jurisdiction (AHJs). The enclosed design includes ample internal space for secure cable termination, making installation faster and minimizing wiring errors on site.
