AP12-1-64F-1251 is a two-pole, fully sealed magnetic circuit protector designed for DC circuit protection with a 64F delay characteristic and 1.25 ampere nominal rating. This protector combines power switching with accurate, reliable circuit protection featuring inverse time delays and trip-free operation, with a peak amplitude trip threshold of 13 times rated current at 60Hz. The unit features toggle-style operation with mounting provisions including a 3/8-32 NEF-2B hex nut and keyway, and weighs approximately 1.8 ounces (49 grams) per pole. The auxiliary switch is rated for 3.0 amperes at 120 VAC or 50 VDC, providing additional control and monitoring capabilities. This protector is ideal for aerospace, military, and industrial applications requiring precise, temperature-independent circuit protection without the thermal drift limitations of conventional thermal protectors.
