AP12-1-72F-752 is a two-pole magnetic circuit protector designed for 50/60Hz applications with a 7.5 ampere nominal rating and short time delay (72F) characteristics. This fully sealed hydraulic magnetic circuit protector combines power switching with accurate, reliable circuit protection featuring inverse time delays and trip-free operation. The unit features a peak amplitude trip threshold of 6.5 times rated current at 60Hz, with trip time ranges from 0.5 to 5 seconds at 125% current and 0.07 to 0.7 seconds at 200% current. Unlike thermal protectors, the AP series maintains consistent trip current performance across wide temperature spans and is available in toggle configuration with mounting provisions for panel integration. The protector is ideal for applications requiring dependable overcurrent protection in industrial control systems, power distribution circuits, and equipment where precise time-delay coordination is essential.
