IELK111-1-63-50.0-AEK-01-V is a three-pole hydraulic magnetic circuit protector from the IEL series, designed for low-cost power switching and reliable circuit protection in international applications. This VDE-approved device features a 50/60Hz motor start delay (63 delay curve) with a 50.0 amp current rating and stud terminals (K designation). The unit provides accurate circuit control with no trip at 100% rated current and trip times of 50 to 700 seconds at 125% and 30 to 400 seconds at 150% of rated current. With an impedance of approximately 0.0018 ohms at 50/60Hz for 50A rating, it offers minimal power loss during normal operation. Common applications include equipment requiring VDE compliance where hydraulic magnetic protection with motor start characteristics is needed.
