*1: 110 V and 220 V can be connected directly. An externally mounted voltage transformer (VT) is needed for voltages greater than those (primary voltage of up to a maximum of 6,600 V).
*2: 110 V, 220 V and 440 V can be connected directly. An externally mounted voltage transformer (VT) is needed for voltages greater than those (primary voltage of up to a maximum of 6,600 V).
*3: 63.5 V / 110 V - 277 V / 480 V can be connected directly. An externally mounted voltage transformer (VT) is needed for voltages greater than those (primary voltage of up to a maximum of 6,600 V).
*4: The settable primary current when using a 5A current sensor is as follows:
5A、 6A、 7.5A、 8A、 10A、 12A、 15A、 20A、 25A、 30A、 40A、 50A、 60A、 75A、 80A、 100A、 120A、 150A、 200A、 250A、 300A、 400A、 500A、 600A、 750A、 800A、 1000A、 1200A、 1500A、 1600A、 2000A、 2500A、 3000A、
4000A、 5000A、 6000A
(The CT primary side can be freely specified up to 6,000 A. However, the CT secondary side is fixed at 5 A.)
*5: Refer to "Specifications: Options (Split Current and 5A Current Sensors)" on p. 19 for the current sensor error ratios.
