Schneider Electric A9MEM1540 PowerTag Energy M63 3P 63 A Top Bottom Mounted Wireless Energy Sensor

The Schneider Electric A9MEM1540 PowerTag Energy M63 is a 3P wireless energy sensor rated 63 A maximum current (10 A base current), top or bottom of the breaker. Its three-pole Monoconnect body covers a full 380-415 V three-phase circuit with a single sensor, mounted above or below the breaker. It reports active energy, active power, current, voltage and power factor to IEC 61557-12 Class 1 accuracy over a 2.4 GHz IEEE 802.15.4 radio link to a PowerTag-compatible concentrator.

Selection Notes

Use the A9MEM1540 to monitor a three-phase circuit without neutral in a single clip-on sensor, avoiding the three single-pole A9MEM1520 units that would otherwise be needed per phase. Where the circuit also carries a neutral conductor that needs monitoring, the 3P+N A9MEM1541 (top) or A9MEM1542 (bottom) is the correct part instead.
