LEM HTR 100-SB Current Transformer 100A 12V, 15V 21mm Bore, Panel Mount, Molex Terminal

The LEM HTR 100-SB Current Transformer is a high-performance current sensor designed for measuring direct, alternating, and pulsed currents up to 100A. With its split-core circular design, the unit ensures easy installation and robust galvanic isolation, suitable for a wide range of electrical monitoring and process control environments. The transformer operates efficiently with supply voltages of 12V or 15V, offering flexible compatibility in automation and electrical systems.

The device features a 21mm bore diameter, supporting various conductor sizes, and utilizes a Molex terminal connector (5045-04/AG) for dependable panel mounting. Compact dimensions of 46mm width and 21.5mm depth allow convenient integration without occupying excessive panel space. The HTR 100-SB is engineered to operate within a broad temperature range from -10°C to 70°C, making it suitable for demanding industrial and process control applications.

For safety and reliability, the current transformer complies with UL 94-V0 flammability rating as well as EN 50178 and IEC 61010-1 standards. Capable of handling dynamic signals, it supports a maximum operating frequency of 10kHz. Its lightweight build, at approximately 80g, enables easy handling and reduces mechanical stress in mounting.

Industrial use cases include process control, electrical protection systems, energy monitoring, automation equipment, and laboratory measurement setups. The galvanic insulation feature ensures safe separation between measured current and output signals, preventing interference in sensitive circuits. The open diameter and split-core construction further simplify retrofitting onto installed conductors.
