BESCHRIJVING

AP17-1-72F-153 is a fully sealed, single-pole magnetic circuit protector designed for 50/60Hz operation with a short-time delay characteristic and a nominal current rating of 15 amperes. This hydraulic magnetic circuit protector combines power switching with accurate, reliable circuit protection featuring inverse time delays and trip-free operation. The unit exhibits a peak amplitude trip threshold of 6.5 times rated current at 60Hz, with a DC series resistance of 0.006 ohms at 100% rated current, and an auxiliary switch rating of 3.0 amperes at 120 VAC or 50 VDC. The protector maintains consistent trip current performance across a wide temperature span, unlike thermal circuit protectors, and is available in series configuration with optional auxiliary switch capability. This device is ideal for applications requiring reliable overcurrent protection in industrial control systems, power distribution circuits, and equipment where temperature-independent protection and precise time-delay characteristics are essential.
