DESCRIPTION

The AP12-1-65F-203 is a fully sealed, two-pole magnetic circuit protector designed for DC circuit applications with a 20-ampere nominal current rating and 65F delay characteristic. This hydraulic magnetic circuit protector combines power switching with accurate, reliable circuit protection featuring inverse time delays and trip-free operation. The 65F delay code provides a peak amplitude trip threshold of 13 times rated current at 60Hz, with trip times ranging from 9 to 60 seconds at 125% rated current and 1.15 to 7 seconds at 200% rated current. The unit features a toggle-style two-pole configuration with hook terminals and an auxiliary switch rated at 3.0 amperes at 120 VAC or 50 VDC. With a weight of approximately 1.8 ounces (49 grams) per pole and operating temperature range of -40°C to +65°C, this protector is ideal for aerospace, military, and industrial applications requiring precise overcurrent protection without temperature-dependent trip current variation.
