3-phase supply control relays model RM4 T Schneider

buiding

 
Giám sát mạch điện 3 pha, bảo vệ động cơ và các loại tải khác trước sự cố nguồn
- Thứ tự pha (tất cả các loại)
- Mất một hay nhiều pha (tất cả các loại)
- Sụt áp (RM4 TU)
- Sụt áp và quá áp (RM4 TR)
- Lệch pha (RM4 TA)
Ứng dụng
- Bảo vệ đấu nối các thiết bị di động (xe lạnh, xe cẩu..)
- Bảo vệ người và thiết bị trước tai nạn gây ra do động cơ quay ngược khi bị đảo pha
- Bảo vệ quá tải khi mất 1 pha.
- Chuyển đổi nguồn dự phòng
