LEM HASS 100-S Current Transformer, 100A, 5V, Hall Effect, Panel Mount, 20mm Bore, -40°C to 105°C

The LEM HASS 100-S Current Transformer is engineered for high-precision measurement of electrical currents in industrial, automation, and process control environments. As a part of the HASS 50..600-S Series, it utilizes Hall Effect sensing technology to achieve accurate detection of both direct and alternating currents up to 100A. It is specifically designed for applications requiring galvanic isolation, reliability, and ease of installation.

This transformer supports a 100A primary current and features a 20mm bore, enabling easy installation over large conductors or busbars. The panel mount construction and Molex terminal interface offer robust integration in control gear, switch panels, and electrical cabinets. With a 5V supply voltage, it aligns with standard industrial electronics and automation requirements.

Durability is assured across demanding operational conditions, as indicated by its extended temperature range from -40°C to 105°C. The compact enclosure measures 40mm in length, 22.8mm in width, and 32.4mm in depth, ensuring space-efficient deployment. Weighing just 55g, it minimizes structural load and is suitable for installations where panel weight is a consideration.

The HASS 100-S is compliant with EN 50178 electrical safety standards, confirming suitability for process control and measurement environments. Its Hall Effect principle enables galvanic insulation, protecting secondary systems and facilitating safe integration into complex networks.

Industrial use cases include electric power distribution monitoring, process control instrumentation, HVAC systems, manufacturing automation, motor drives, and energy management systems. The device offers versatility for DC, AC, pulse, or combined signal monitoring.
