CCM Single-phase current meter, pack of 2

The CcM1-C is a current measurement device designed for use within the CcM product family, which is ideal for monitoring AC current in electrical installations. It operates by measuring the current using a magnetic sensor and transmitting the data via Modbus RTU over an RS-485 communication cable. This device is intended for integration within thermal-magnetic switches or residual-current circuit breakers, both in single-phase and three-phase systems.

Key features include a current measurement range from 0.2 to 63 Arms with an accuracy of less than 1% full scale, and it communicates through a Modbus RTU protocol. It also provides rapid response time (0.1 seconds) and operates at a typical power consumption of 360 mW with a 12 VDC supply. Its compact design, with dimensions of 42 x 18 x 26 mm, makes it suitable for tight installations in electrical panels. The CcM1-C is designed to function as a secondary device connected to a principal device (CcM4, CcM3, or CcM2), which acts as the master unit in the system. This system allows users to create flexible configurations for both domestic and industrial applications.
