The AP12-1-62-302 is a fully sealed, two-pole magnetic circuit protector designed for 50/60Hz AC circuits with a long time delay characteristic and a nominal current rating of 3.0 amperes. This hydraulic magnetic circuit protector combines reliable power switching with accurate circuit protection, featuring an inverse time delay and trip-free operation that does not change its trip current over a wide temperature span. The unit has a DC series resistance of 0.130 ohms for long delay operation and an auxiliary switch rating of 3.0 amps at 120 VAC/50 VDC, with an approximate weight of 1.8 ounces (49 grams) per pole. The AP12-1-62-302 is ideal for applications requiring stable, temperature-independent circuit protection in industrial power distribution systems, control circuits, and equipment where precise overcurrent protection with delayed response is essential.
