Smart Power Meter Shelly PRO 3EM-3CT63

DIN Rail Mountable, Single or Three-Phase Energy Meter

The Shelly Pro 3EM-3CT63 is a DIN rail mountable energy meter that supports both single-phase and three-phase installations. It comes with a combined three-phase current transformer (CT), designed for direct mounting above a circuit breaker. This device accurately measures energy consumption and is ideal for various applications, including industrial machinery monitoring, home and office energy savings, and electrical load management.

IMPORTANT! This device does not have an integrated relay. A contactor is controlled via a Shelly Pro add-on, which must be attached to the Shelly Pro 3EM-3CT63.

Key Features:

✔ 4-Quadrant Measurement – Measures both capacitive and inductive loads, including imported and exported active energy.
✔ DIN Rail Mounting – Designed for seamless integration into electrical systems.
✔ Flexible Connection Options – Supports single-phase and three-phase installations.
✔ Non-Contact Current Transformer (CT) Connection – Ensures easy and accurate measurement.
✔ Optical Pulse Display – Provides visual feedback on energy consumption.
✔ Real-Time Clock (RTC) – Maintains correct time stamps even if the internet connection is lost.
✔ Data Logging – Stores up to 60 days of energy data for later retrieval.
✔ External Contactor Control – Allows automated control of loads via Shelly’s scripting functions. (Requires the additional Shelly 3EM Switch add-on.)
✔ Photovoltaic Compatible – Ideal for solar energy monitoring and management.

Why Choose the Shelly Pro 3EM-3CT63?

Professional-Grade Energy Meter

The Shelly Pro 3EM-3CT63 measures both accumulated energy and real-time electrical values, including:

• Voltage per phase/channel
• Current per phase/channel
• Active and apparent power per phase/channel

It securely stores measurement data in non-volatile memory and allows retrieval at one-minute intervals for up to 60 days. The built-in real-time clock (RTC) ensures that time synchronization remains accurate, even if SNTP server connection is lost.

Advanced Functions:

LAN, Wi-Fi, and Bluetooth Connectivity

• LAN Connectivity – Ensures high security and reliability for industrial environments.
• Dual Network Support – Wi-Fi and LAN can operate simultaneously, ensuring a failover connection in case one goes offline.

High-Precision Energy Monitoring

• 1% Accuracy (Class B) – Ensures highly accurate energy measurement.
• Supports Three Measurement Points – Monitors three circuits simultaneously.
• Fast Notifications – Real-time alerts on energy consumption changes.

Industrial-Ready: MODBUS Support

• MODBUS Integration – Easily integrates into existing industrial automation systems for remote monitoring and control.

Advanced Scripting Capabilities

• mJS Scripting Support – Enables advanced automation without the need for an external server.
• Custom Automation & Controls – Create custom energy management scenarios tailored to your needs.

The Shelly Pro 3EM-3CT63 is an essential tool for professional energy monitoring, industrial applications, and smart home energy management, offering unmatched accuracy, reliability, and automation.
