Shelly 50A - Current transformer clamp

The Shelly 50A Current Transformer (SHELLY-50A) is an accessory for residential and commercial energy monitoring. It measures electrical loads up to 50 A without requiring modifications to existing wiring. The clamp fastens around a live conductor to measure current flow, transmitting the data to a connected energy meter that calculates power consumption and other electrical parameters. This non-invasive method allows for safe monitoring in both single-phase and three-phase installations.

Designed for the Shelly ecosystem, this transformer acts as an expansion sensor rather than a standalone device. It relays real-time current data to a monitoring hub, providing oversight of high-draw circuits or individual appliances. Its form factor fits within standard distribution boards alongside circuit breakers. Electricians and homeowners use it to track energy usage patterns across different zones of a property.

• Compatible with Shelly meters: Integrates directly with Shelly EM, Shelly Pro EM, and Shelly Pro 3EM devices.
• 0.6 m integrated cable: Provides sufficient length for connecting the sensor to a hub within an electrical panel.
• 10 mm conductor capacity: Accommodates wiring up to 10 millimetres in diameter for standard circuit installations.
• 26 mm x 27 mm x 42 mm dimensions: Compact footprint minimises space requirements inside crowded consumer units.
• 100 g weight: Lightweight construction avoids putting strain on the measured cables.
