Description ECM800 low voltage motor protection and control device is designed for protecting the low voltage motors from various fault conditions. It is an intelligent unit with high cost-effective and stability. It integrates relay protection, measurement, control and communication all in one,
ECM800 samples the 3- phase current, 3-phase voltage, zero-sequence current. The data are then applied to the algorithms and compared to the device¡¯s configuration information. Based on the result of the comparison, the controller may trip one or more of the on-board control relays. Feature - Compact designed integrates measurement, protection, control and communication
