CM-60 Protection Controller for Low-Volt Motor

CM-60 series protection controllers are designed to provide full-scale protections and controls of low-voltage asynchronous motor and increasing safety motor rated below 800A, 50Hz, 380VAC. CM-60 measures the electrical parameters of motors, operates and controls the motors ,and equipped with the history record management and remote communication function.

CM-60 products portfolio: standard CM-60-1S and CM-60-3S, popular CM-60-2M and integrated CM-60-2P. With different infrastructure, installation, and functions, these four types of protector controllers can meet different requirements of customers in low-voltage protection area.
