CCM 3-phase current meter

Current measuring devices

The CcM3-C is one of the devices from the CcM product range, which serves to measure AC current using magnetic sensors and to deliver these data via Modbus RTU connection using an RS-485 cable. The CcM meters product range consists of a set of devices used for the monitoring of electrical parameters inside electrical switchboards in single- and three-phase installations. It is best suitable for installation in thermal-magnetic switches or residual-current circuit breakers.

Specifically, the CcM3-C is part of the CcM product range devices known as “secondary” (CcM1-C and CcM3-C) because they only exist inside the secondary bus where the “principal” devices from the CcM family (CcM4, CcM3, and CcM2) act as masters sending requests to the secondary devices as slaves.

Unlike the “principal” devices from the CcM family, which are connected to the principal communication bus directly and can measure current, voltage, power, energy and harmonics distortion, the CcM3-C is connected to the secondary bus of any of the principal devices and only measures current.
