FAQs:

1. Can this isolator be used in systems with voltages higher than 500V DC?
   No, this isolator is rated for a maximum working voltage of 500V DC. For higher-voltage systems, a different isolator with the appropriate voltage rating should be used.

2. Is the isolator suitable for outdoor installations?
   This isolator has an IP40 ingress protection rating, meaning it’s protected from solid objects larger than 1mm, but not from water. It is ideal for indoor use or within a weatherproof enclosure for outdoor installations.

3. How do I reset the isolator after it trips?
   Once the cause of the trip (overload or short circuit) is addressed, the isolator can be manually reset by switching it back to the “ON” position.
