The IEGS11-1-63-20.0-01-V is a single-pole hydraulic magnetic circuit protector designed for reliable circuit protection and power switching in IEC-compliant equipment. This device features a 50/60 Hz motor-start delay (Delay 63) with a rated current of 20.0 A and operates with series internal configuration and auxiliary switch capability (.110 quick connect terminals). The protector meets IEC spacing requirements mandatory for IEC 601, 950, and VDE 0804, 0805 specifications, and is UL Recognized as a supplementary protector per UL STD. 1077 and CSA Certified. It provides accurate circuit control with trip characteristics ranging from 30 to 400 seconds at 150% rated current down to 0.013 to 0.5 seconds at 1000% rated current. The device is ideal for protecting sensitive electronic circuitry and dense packaging in automation systems where motor inrush current accommodation is required.
