Circutor Cirwatt B 212-ES7A-21B20 Single-Phase Energy Meter

CIRWATT B 101-102 are single-phase residential meters with class B (class 1) inactive energy and class 2 in reactive energy. It has 4 tariffs and a flexible configuration. An advanced design offers high features and versatility to fulfill requirements in domestic applications. These meters have a memory to record load profile for 400 days, 12 billing closures, and moreover tamper registers and power quality information. As an option, it has a backlight display to help in reading energy consumptions or any other information showed if there is not enough light. It includes PLC (Power Line Carrier) Communications through a power cable and an optical communications port. Both use the IEC-61870-5-102 protocol. In addition, it can display information in case of power loss just by pressing the button, it can store up to 6 channels of energy registers with 3 months of hourly load profile and it can limit maximum power consumed by end-user, through an internal disconnection relay which can be remotely managed using PLC communications

The main application of the meter is the metering of active CIRWATT B and reactive energy for billing purposes, whenever a meter with high-performance features is required at an optimized cost. PLC communications can be used for the remote download of all data recorded by the meter through a PLC-800 concentrator. The circuit breaker integrated into the meter can be used to manage the supply remotely, opening/closing the circuit breaker and programming the hired power above a value that will activate the circuit breaker, opening it, and reclosing it to guarantee the safety of the final user
