Strong Points
Function
Primary rated currents. Their 333 mV output signal makes them compatible with DIRIS A-100/A-200 (333 mV models), WattNode and DIRIS MCM power meters, or any third-party meter accepting 333 mV current sensors.
The TR-W series' compactness and low-voltage output signal make it ideal for retrofit applications with existing electrical panels that have limited space.
Conformity to standards
UL 61010, CSA-C22.2 No.61010, File E257746
IEC 61869-2
Advantages
Plug & Play
- The split-core concept facilitates installation without disconnecting electrical wires inside the panel.
- The built-in burden resistor provides 333 mV voltage output at the rated full-scale current, eliminating the need for shorting blocks.
Long lead wires
The TR-W series comes with standard 22-ft / 7m twisted pair lead wires, ideal for remote meter installation. This reduces installation downtime and costly wire extensions and materials, which typically increase the risk of wiring errors.
Compact
The compact design of the TR-W split-core series makes them ideal for applications where space is limited, such as existing panelboards
Accurate
The TR-W split-core sensors deliver a 0.5% accuracy per IEC 61869 over a wide range from 10 – 120% of the rated current, essential for accurate power and energy measurements.
Tamper proof
The TR-W current sensors can be sealed to prevent and detect possible tampering, which would alter energy readings.
