The CNC YCB8-63PV 4P+4P DC 1000V 63A MTS Breaker Type is a high-performance manual transfer switch designed for dual power systems, especially in solar photovoltaic (PV) installations. It enables safe and efficient switching between two DC power sources such as solar arrays and battery backup systems.
With a 4P+4P configuration, this device ensures complete isolation of all lines, providing enhanced safety and preventing backfeed or short circuit risks. It is specifically engineered for high-voltage DC environments, supporting up to 1000V DC and 63A current capacity, making it suitable for medium to large solar systems.
The breaker-type MTS design combines switching functionality with circuit protection, offering overload and short circuit safety for connected equipment. Its thermomagnetic trip mechanism ensures fast response during faults, protecting sensitive solar components such as inverters, batteries, and PV strings.
Built according to IEC/EN 60947-2 standards, the YCB8-63PV series guarantees durability, high breaking capacity (up to 6kA), and long operational life. The modular DIN rail design allows easy installation in solar combiner boxes and DC distribution panels.
This breaker is widely used in photovoltaic systems, industrial DC setups, and communication systems where stable and safe DC power management is critical.
