The AP12-1-72-752 is a two-pole magnetic circuit protector designed for DC applications with short time delay characteristics and a nominal amperage rating of 7.5 amperes. This fully sealed unit combines power switching with accurate, reliable circuit protection featuring inverse time delays and trip-free operation. The protector maintains consistent trip current performance across a wide temperature range, unlike thermal circuit protectors, and is available with various delay configurations to match specific application requirements. The unit features an auxiliary switch rating of 3.0 amps at 120 VAC or 50 VDC, with a weight of approximately 1.8 ounces per pole. Common applications include power distribution systems, motor control circuits, and industrial equipment where reliable overcurrent protection and precise time-delay response are essential.
