Các model Mô-đun điện trở nhiệt bảo vệ động cơ Siemens SIRIUS 3RN2 | SIRIUS 3RN2 thermistor motor protection

dùng để theo dõi trực tiếp nhiệt độ cuộn dây của động cơ. Động cơ được trang bị điện trở phụ thuộc nhiệt độ (PTC) được lắp trực tiếp vào cuộn dây động cơ và thay đổi đột ngột điện trở của chúng ở giới hạn nhiệt độ của chúng. Bảo vệ động cơ trực tiếp thông qua giám sát nhiệt độ của cuộn dây động cơ giúp bảo vệ động cơ 100% ngay cả trong các điều kiện môi trường khó khăn nhất mà không cần phải điều chỉnh trên thiết bị. Bảo vệ động cơ như - Ở nhiệt độ môi trường xung quanh tăng lên, - Khi tần số chuyển mạch quá cao, - Khi quy trình khởi động và phanh quá dài..
