Current Transformer Shelly 50A Black

The Shelly 50A Current Transformer in black is a compact sensor designed to measure alternating current up to 50 A. Intended for integration with monitoring and automation systems, this current transformer delivers analog input for energy measurement and supports installation in residential and light-commercial electrical panels. The black housing and small footprint allow for discreet placement near mains conductors without occupying significant panel space.

Advantages

The device offers reliable measurement of current up to 50 A with a compact form factor that facilitates installation in tight spaces. Its simple design and DIN-rail or cable-through mounting compatibility simplify retrofitting existing electrical installations. The transformer provides consistent readings for energy monitoring and helps improve visibility into consumption patterns, supporting more informed energy management decisions.

Suitable for

• Monitoring household energy consumption and load profiling
• Integration with home automation and smart energy systems
• Measuring current on single-phase circuits up to 50 A
• Retrofitting distribution boards and meter cabinets

Key specifications

• Maximum measurable current: up to 50 A
• Color: black housing
• Form factor: compact, cable-through/current-clamp style
• Intended use: AC current measurement for energy monitoring
• Typical installation: electrical panels, meter enclosures, near conductors

How to use

Install the Shelly 50A Current Transformer by passing the conductor through the transformer's aperture according to the polarity mark and mounting the unit securely in the panel. Connect the transformer's output to the compatible Shelly or other supported monitoring device following the manufacturer's wiring instructions. Calibrate or configure the monitoring system to recognize a 50 A sensor where required, and verify readings under known load conditions to confirm correct setup.

Recommendations

Use the current transformer only on circuits within the specified 50 A rating and ensure all installation and wiring is performed with power isolated and in accordance with local electrical regulations. For reliable measurements, position the conductor centrally in the aperture and avoid placing multiple conductors through the transformer. Refer to the connected energy monitor's configuration options to set correct scaling and sampling parameters.
