Overview
IAMMETER WEM3080TD-150 is the Delta-system member of IAMMETER's three-phase Wi-Fi meter family. It is built for 3-phase 3-wire Delta monitoring first, while IAMMETER's current quickstart also documents split-phase and single-phase support.
Core fit
- Designed for Delta sites that do not have a neutral wire.
- Uses CT-based measurement with a 150A variant in the current official purchase guide.
- Supports local API, MQTT, HTTP or HTTPS, Modbus TCP, and Home Assistant-oriented integration paths.
- Keeps cloud use optional instead of mandatory.
Installation notes
IAMMETER's current quickstart is explicit that WEM3080TD is the right choice for 3-phase 3-wire Delta systems, while WEM3080T should be used for 3-phase 4-wire WYE or Star systems. In standard Delta wiring, phase B is the reference phase and CTa plus CTc are used in the normal measurement layout.
Why this matters
That wiring distinction affects real buying decisions. A meter that is correct for WYE systems is not automatically the right fit for Delta panels, compressors, motors, or other three-wire commercial and industrial loads. WEM3080TD is the safer IAMMETER path when Delta support is the deciding requirement.
Buying context
IAMMETER's current global purchase guide lists a 150A WEM3080TD reference-price lane at 168 USD. Buyers who need more headroom should compare the higher-current WEM3080TD variants rather than assuming the 150A version is enough.
