ABB OTDCP16SA22MD enclosed DC solar switch rated at 16 A and 1000 V DC with a four-pole design, IP65 enclosure and red-yellow rotary handle for photovoltaic and battery storage systems.
The ABB 1SCA131850R1001, also known as the OTDCP16SA22MD, is a premium enclosed DC switch disconnector engineered for the safe isolation of photovoltaic arrays, battery energy storage systems and other direct current installations. Rated at 16 A with a maximum operational voltage of 1000 V DC, it delivers dependable switching performance for modern renewable energy applications.
Built within ABB's durable OTDCP enclosed solar switch range, the switch features a rugged UV-resistant glass reinforced polycarbonate enclosure with an IP65 protection rating, making it suitable for demanding indoor and outdoor environments. Threaded cable entries with knock-out holes allow straightforward installation for photovoltaic and battery storage systems.
The four-pole design incorporates a red and yellow rotary selector handle, an interlocked cover and a handle that can be secured with up to three padlocks, helping improve maintenance safety and prevent unauthorised operation. Its compact enclosure makes it ideal for solar combiner boxes, inverter isolation and industrial DC distribution systems.
Enclosed DC switch disconnectors provide a safe means of isolating live DC circuits before maintenance or inspection. In photovoltaic installations, they allow solar arrays to be disconnected from inverters, while battery storage systems benefit from secure isolation during servicing and emergency shutdown procedures.
The ABB OTDCP16SA22MD combines durable construction, weather-resistant protection and dependable switching performance to support long-term reliability in residential, commercial and industrial renewable energy installations.
