The IULNK1-1REC4-62-35.0-A is a three-pole hydraulic magnetic circuit protector designed for 50/60 Hz AC applications with a long-delay trip characteristic (delay code 62) and a rated current of 35.0 A. This device provides reliable circuit protection and power switching for equipment in the international marketplace, with trip time ranges specified across multiple current levels: at 125% rated current, trip time is 10 to 120 seconds; at 150% it is 6 to 60 seconds; at 200% it is 2 to 20 seconds; and at higher overload percentages, response times decrease progressively to millisecond ranges. The protector features a series configuration with an auxiliary switch (-1REC4 designation with 110 quick connect terminals) and is mounted in the normal vertical position with specifications valid at ambient temperature of -25°C. It is suitable for applications requiring accurate circuit control, reliable protection, and low-cost power switching in industrial and international equipment.
