YCM3RT Thiết bị đóng cắt MCCB (Cầu dao tự động MCCB) là sản phẩm mới, nhỏ gọn, dạng mô-đun, ngắt cao, điểm ngắt kép, không hồ quang, bảo vệ môi trường xanh. Thích hợp cho mạng lưới phân phối AC 50Hz, 60Hz, điện áp hoạt động định mức 690V trở xuống, dòng điện định mức 12,5A đến 1600A, được sử dụng để phân phối năng lượng điện và các đường dây bảo vệ và thiết bị cung cấp điện khỏi nguy cơ quá tải, ngắn mạch và hỏng điện áp thấp. Nó cũng có thể được sử dụng như một chuyển đổi không thường xuyên của đường dây trong điều kiện bình thường và khi động cơ khởi động không thường xuyên
