LEM AT-B10 Series Current Transformer 5 A 16 mm Bore, Cable Mount, IEC 61010-1 Rated AT 5 B10

LEM AT 5 B10 is a high-precision current transformer designed for electronic measurement of alternating currents in industrial and automation applications. The sensor provides galvanic insulation between the primary and secondary windings, ensuring electrical safety and accurate signal transmission.

This model features a 16 mm bore diameter, allowing it to accept cables up to 16 mm, making it suitable for integration in control systems with compact cable arrangements. The transformer operates with a primary current rating of 5 A and supports operating frequencies from 50 Hz up to 60 Hz, accommodating a wide range of industrial AC current sensing requirements.

Constructed for cable mounting, it uses an M3 connector terminal for secure and reliable wiring. Its compact size - 51 mm length, 40.5 mm width, and 36.5 mm depth - combined with a light weight of 90 g enables flexible installation in tight spaces.

The AT B10 series meets stringent safety standards including IEC 61010-1 and UL 94-V0 flame retardant rating, making it compliant for industrial automation environments. It operates efficiently across a temperature span from -20°C to 60°C, suited for varied climatic conditions in manufacturing, process control, and electrical distribution systems.

Typical use cases include industrial process control, power monitoring, electrical distribution panels, and automated equipment that require high-fidelity current sensing with electrical isolation for both safety and functional integrity.

This current sensor provides galvanic insulation for safe alternating current measurement. 5 A primary current rating with 16 mm bore diameter supports standard conductor sizes. Compact cable mount design with M3 connector terminals enables easy installation.
