Shelly 3EM-63T energy meter Gen3 (flat terminal)

What is the Shelly 3EM‑63T Gen3 (Flat Terminal Model)? The Shelly 3EM‑63T Gen3 is a compact energy meter with flat terminals designed to measure a three-phase installation or three separate single-phase circuits. The meter supports 4-quadrant metering and is Solar System (PV) ready, making it suitable for situations where both consumption and (solar) generation are relevant. In the "flat terminal" (T) model, the energy meter's connection points are flat and compact. This design is ideal for applications where space is limited, such as in a crowded meter cabinet. The Flat Terminal Model of the Shelly 3EM-63T is used to easily mount the meter above or below a DIN rail circuit breaker without cables taking up too much space. What values ​​do you measure (real-time)? The Shelly 3EM‑63 Gen3 (including the 63T variant) records voltage, current, active and apparent power, and the associated energy values, plus power factor, in real-time per phase. This allows for thorough analysis of energy flows and load behavior per phase. Data Logging & Timestamps * Local storage: Data is stored in non-volatile memory and can be retrieved for up to 7 days at 1-minute intervals. * Real-time clock: Timestamps remain accurate, even in the event of SNTP/connection loss. Connectivity & Integrations (Local or Cloud) The meter can operate standalone in a local Wi-Fi network or communicate via cloud/home automation services using MQTT, HTTP, and WebSocket. It is noted that all inbound connections support TLS. Additionally, there is an embedded web interface for monitoring, configuration, and operation. Installation: Compact and Space-Saving The described installation is space-saving due to mounting above or below a DIN-rail mounted circuit breaker. For the 63T variant, the dimensions are 31×54×42 mm (without wire) and the weight is 52 g (incl. wire). Additional features for installers * Phase sequence fault detection with zero-crossing operation detection. * No load threshold: the no-load threshold is 30 VA per channel. Below this, power is displayed, but no energy is summed (with notification in web interface/app). * Optical pulse indication via LED indicator for visual feedback. * Accuracy class B according to IEC 62053‑21.
