The IEG11-1-61F-30.0-91-V is a two-pole hydraulic magnetic circuit protector designed for reliable power switching and circuit control. It features a 30.0A current rating for 50/60Hz applications, a series trip configuration, and a short time delay curve (61F) with an inertial delay feature that provides a pulse tolerance of approximately 12 times the rated current. The hydraulic magnetic design ensures precise operation across a wide temperature range of -40°C to +85°C, unaffected by ambient temperature changes. As a VDE-approved component meeting IEC spacing requirements, it is ideal for applications in data processing, medical instrumentation, and broadcast equipment.
