FAQs:

1. Can this isolator be used in systems with voltages higher than 500V DC?
   No, the MCB 500V 2P 32A DC Solar Isolator is rated for a working voltage of up to 500V DC. For systems with higher voltages, a different isolator with the appropriate voltage rating should be selected.

2. Is the isolator suitable for outdoor installations?
   The isolator is rated IP40, meaning it’s protected from solid objects larger than 1mm but not from water. For outdoor use, it is recommended to install it within a weatherproof enclosure.

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