Schneider Electric WHD20 Surface Mount Double Pole Isolating Switch designed for electrical applications. The switch is designed to handle a maximum current of 20 Amperes. This means it is suitable for circuits with a load of up to 20A. It is rated to handle a maximum voltage of 440 Volts. It's important to never exceed this voltage to ensure safety and proper operation.

The switch has two sets of contacts that can be used to simultaneously disconnect two conductors. This is useful for applications where you need to isolate both the live and neutral wires. The IP66 rating indicates that this switch is dust-tight and protected against powerful water jets. This suggests that it's suitable for outdoor applications or environments where it might be exposed to harsh conditions.

Overall, Schneider Electric WHD20 Surface Mount Double Pole Isolating Switch is designed to provide a safe and reliable means of isolating electrical circuits.
