TOMZN 2P+2P MTS DC Dual Power Circuit Breaker For PV System
The TOMZN 2P+2P DC MTS Dual Power Manual Transfer Switch with Integrated MCB is a manual changeover device specifically designed for DC dual‑power photovoltaic (PV) systems. It supports a maximum DC voltage of 1000 V and comes in a range of current ratings (e.g., 6 A up to 63 A) to match different PV and battery load requirements. The switch enables safe manual transition between two DC power sources (such as solar array and battery bank), while the built‑in MCB provides overload and short‑circuit protection to safeguard system components. Its robust, flame‑retardant design and DIN‑rail‑mountable construction make it suitable for use in solar PV combiner boxes, DC distribution panels, and energy storage systems where reliable manual control and safety are required.
