3CT Zigbee Energy Meter, 120A
Description
For installations that need more power. The 3CT Zigbee Energy Meter 120A from NodOn measures up to 120 A per phase with high accuracy. It is designed for high-current electrical installations: commercial buildings, large homes, or high-power photovoltaic systems, in both single-phase and three-phase setups.
It reports real-time voltage, current, instantaneous power, and cumulative energy for each phase. Its bidirectional measurement tracks both consumed and produced energy.
This lets you optimize your self-consumption, manage electric vehicle charging based on available solar surplus, and apply load shedding to control consumption peaks.
Despite its high measurement capacity, the module stays ultra compact and clips onto a single DIN slot (18 mm). Its three opening current clamps, reinforced to support up to 120 A, fit around the cables without any intervention on the conductors: a fast setup, for both renovation and new installations.
It is 100% Zigbee 3.0 interoperable and connects to most Zigbee home automation hubs on the market. Updates are performed remotely (OTA), directly from your hub.
