IEGH111-1-61-20.0-01-V is a single-pole hydraulic magnetic circuit protector designed for low-cost power switching and reliable circuit protection in equipment requiring IEC compliance. This unit features a 50/60 Hz short delay characteristic (delay code 61) with a rated current of 20.0 amperes, meeting IEC spacing requirements mandatory for IEC 601, 950, VDE 0804, and 0805 specifications. The protector is equipped with a toggle handle per pole (H designation) with black color and ON-OFF marking (-01 designation), and includes VDE and CCC approval (V designation). The device provides accurate circuit control for sensitive circuitry and denser packaging in automation systems, with typical AC impedance of 0.006 ohms at 50/60 Hz and 0.010 ohms at 400 Hz for the 20.0 A rating. Applications include protection of industrial equipment, automation systems, and sensitive electronic circuits where reliable overcurrent protection and compliance with international standards are essential.
