Feature: 1. Maximum connection capacity 25mm, wiring torsion 3.5N.m, suitable for various installation equipment. 2. Bilateral busbar wiring capacity to accommodate a wider range of uses. 3. When someone encounters an electric shock or the leakage current exceeds a fixed value, the power supply can be cut off. 4. In order to protect the person and equipment, the short‑time fault current can also be used for the circuit and motor's not‑frequent starting. 5. The circuit breaker is suitable for industrial, commercial, high‑rise buildings, homes and other places.
