YCH8DC DC Isolation Switch
YCH8DC DC Isolation Switch
YCH8DC DC isolation switch is suitable for DC systems with rated voltage up to DC1500V and rated current up to 800A, playing a role in DC circuit isolation and helping the system operate safely and stably.
Mainly used in DC power supply systems such as photovoltaic power generation DC side,DC power supply system, DC charging pile, energy storage, etc.
Features
1. The switch has no polarity, making the wiring more flexible
2. Clearly visible breakpoints make line maintenance safer
3. Compact size, easy installation, and reliable operation
4. Strong environmental adaptability and wide application
Operating conditions
1.High temperature withstand:no derating upto 70℃
2.Ambient Temperature:-40℃ to+70℃.
3.Humid temperature testing(2 cycles,55°℃/131F with 95%humidity level).
4.Salt mist testing(3 cycles with humidity storage,40℃/104F,93% humidity after each cycle).
