Hello, everyone! I am Lu CaiPing, and I’m working for Ningbo Feiling Electrical Co., Ltd. The meter case is our in-house manufactured product. This type of case is not only applicable to electric meters, but it is also used in the production of gas meters, water meters, rail mount meters etc. The single-phase electricity meter case is divided into electronic type and prepayment type. What you see here is the 009-3 electronic type single-phase electric meter case. It is equipped with an IR optical port for data collection. We have designed this product with protective covers and test buttons, which can stop electricity theft, leakage and so forth. The terminal offers a wide choice of electric current, spanning from 20 A to 80 A, and even an ultra-large current of more than 100 A.
