IALNK1-1REC4-72-80.0 is a single-pole hydraulic magnetic circuit protector from the IAL series, designed for low-cost power switching and reliable circuit protection. This unit features a panel seal configuration (IALN type) with an auxiliary switch (1REC4), DC long delay (72), and is rated at 80.0 amperes. The DC long delay (72) provides trip times suitable for most transformer and capacitor loads, with no trip at 100% rated current and trip times of 1.8 to 100 seconds at 125% rated current. The circuit protector offers pulse tolerance of approximately 10 times rated current for delays 71, 72, and 73. It is ideal for equipment in the international marketplace requiring accurate circuit control and protection where inherent attributes are desired without specific standards compliance.
