Shelly 3EM-63W energy meter Gen3 (wired)

What is the Shelly 3EM‑63W Gen3 (Wire Model)? The Shelly 3EM‑63W Gen3 is a compact energy meter with flexible connection wires (wire model) designed to measure a three-phase installation or three separate single-phase circuits. The meter supports 4-quadrant measurement and is Solar System (PV) ready, making it suitable for situations where both consumption and (solar) generation are relevant. In the "wire model" (W) model, the connection points of the energy meter are equipped with flexible wires. This design is ideal for integration applications in existing distribution boards, especially where the positioning of circuit breakers is difficult. The Wire Model of the Shelly 3EM-63T is used to easily mount the meter in a distribution board with sufficient space and is therefore specifically designed for ease of installation through flexible cabling. What values ​​do you measure (real-time)? The Shelly 3EM‑63 Gen3 (including the 63W variant) records voltage, current, active and apparent power, and the associated energy values, plus power factor, in real-time per phase. This allows you to effectively analyze 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: ease of installation and flexibility Installation is easy and flexible thanks to mounting around the circuit breaker using flexible cabling. For the 63W variant, the dimensions are 21×54×42 mm (without wire), the weight is 58 g (incl. wires), and the wire length is 260 mm (incl. terminal). 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 added (with notification in web interface/app). * Optical pulse indication via LED indicator for visual feedback. * Accuracy class B according to IEC 62053‑21.
