DC Rotary Isolator Switch - Single String - 25A ,IP65
Single String DC isolator switch is used between DC PV arrays and grid-connect inverters. Positioned adjacent to the inverter a DC switch is required to provide a means of manually isolating the entire PV array during system installation or any subsequent maintenance.
This-25DC DC Isolator Switch delivers robust, professional-grade isolation for 25A DC circuits, making it ideal for solar photovoltaic systems, battery storage installations, EV infrastructure and other DC loads that require secure power disconnection. Designed with a rugged IP65 thermoplastic enclosure, this rotary isolator offers protection against dust and water ingress, enabling versatile installation in indoor and outdoor environments where weather resistance is essential. Constructed for both safety and installer convenience, the unit includes on-load switch disconnectors for safe breaking of live circuits, a lockable rotary handle to prevent unauthorised operation, and an interlocked front cover that can only be removed in the OFF position for enhanced protection during maintenance. Multiple M20 cable entry knockouts allow flexible conduit and cable routing, while rising clamp terminals support cables up to 16mm˛.
The unit is built to BS EN IEC 60947-3 standards and complies with DC-PV1 and DC-PV2 utilisation categories, making it suitable for a wide range of DC power applications. Whether you're specifying components for new renewable energy systems or upgrading existing DC installations, the switch combines safety, durability and ease of installation in a weatherproof, trusted design.
