Schneider Electric A9MEM1521 PowerTag Energy M63 1P+N 63 A Top Mounted Wireless Energy Sensor

The Schneider Electric A9MEM1521 PowerTag Energy M63 is a 1P+N wireless energy sensor rated 63 A maximum current (10 A base current), top of the breaker only. It is built for the 18 mm phase-to-neutral pitch used on Acti9/Multi9 1P+N Monoconnect devices and clips on above the breaker only. 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

Choose the A9MEM1521 over the Monoconnect 1P sensor when the circuit already carries a neutral conductor through the breaker and the panel only has clearance above the device -- it is fixed to the 18 mm Ph/N pitch and top position only, unlike the top-or-bottom A9MEM1520. If the breaker sits where only the space below is free, use the bottom-mount A9MEM1522 instead.
