after-sale service:
There is a complete after-sales service system for vacuum circuit breakers from receiving orders to delivering products to customers.

When the product is safely transported to the customer's hands, the customer must carefully inspect it. The specific inspection items are as follows:

1. Check if the packaging is damaged;
2. Check whether the documents, accessories, and spare parts are complete by comparing with the product packing list;
3. Check whether the technical parameters and product qualification certificate on the nameplate of the circuit breaker on the column meet the ordering requirements.

Kind reminder: Before installation after purchase, vacuum circuit breakers must be stored indoors in a dry, ventilated, moisture-proof, shock resistant, and harmful gas resistant environment. When stored for a long time, the environment should be regularly checked to ensure compliance with requirements.

Packing, unpacking, and storage should be carried out in a dry room, and the products and components should be checked for completeness and consistency.
