YCH8DC DC Isolation Switch

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).
