Size 73mm x 57mm x 22mm
The deviation from the device dimensions is up to 0.5mm. The deviation from the case dimensions is up to 2 mm.
* The Device has phase sequence error detection circuits. This detection works on phase voltages and considers only the zero crossings. The regular succession of these zero-crossing events is Phase A followed by Phase B followed by Phase C. If the sequence of zero-crossing events is, instead, Phase A followed by Phase C followed by Phase B, then a phase sequence error is reported, when the Phase sequence error detection option is enabled.
