FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter
Single Phase MID Approved Energy Meter with 100A Split-Core CT Clamp
FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter is a compact single phase multi-function energy meter supplied with a 100A split-core CT clamp for monitoring electrical current and energy consumption.
The split-core CT clamp fits around the monitored conductor, allowing current measurement without passing the main conductor directly through the energy meter. The supplied 100A CT clamp uses a 330mV AC input and includes a 2m connection cable for flexible positioning within the installation.
The FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter supports bidirectional energy measurement, allowing both imported and exported electrical energy to be monitored. Its compact 1-module DIN rail design also makes it particularly useful where space inside the enclosure is limited.
An integrated RS485 Modbus RTU interface enables communication with compatible energy monitoring and building management equipment. The meter can monitor a range of electrical parameters including voltage, current, active power, power factor, frequency and energy usage.

100A Split-Core CT Clamp Included
The FuseBox KWHEM115 is supplied complete with a 100A open-core / split-core CT clamp. The clamp design allows it to be positioned around the conductor being monitored rather than requiring the conductor to pass directly through the meter.
The CT clamp provides a 330mV AC input at a 100A primary current and is supplied with approximately 2m of connection cable.
Bidirectional Energy Monitoring
The FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter provides bidirectional metering for installations where energy flow needs to be monitored in both directions.
It can measure import active energy, export active energy and total active energy. Import and export reactive energy information is also available through the communication interface.
RS485 Modbus RTU Interface
Integrated RS485 Modbus RTU communication allows the meter to connect with compatible monitoring, control and energy management systems.
The FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter provides configurable Modbus communication parameters including baud rate, Modbus ID and parity, allowing integration with compatible monitoring equipment.
Compact DIN Rail Energy Meter
At just 18mm wide, the FuseBox KWHEM115 100A CT Clamp Modbus kWh Meter occupies only one DIN module, providing a space-saving option for consumer units, distribution boards and other suitable electrical enclosures.
