A9F74320
Schneider Electric A9F74320 Acti9 iC60N 3-pole 20 A C-curve miniature circuit breaker. The Schneider Electric A9F74320 is a three-pole Acti9 iC60N miniature circuit breaker rated 20 A with a C tripping curve, built for 380...415 V three-phase final distribution. Its thermal-magnetic trip unit gives overload and short-circuit protection with 6000 A Icn at 400 V AC to EN/IEC 60898-1 and 10 kA Icu at 380...415 V AC to EN/IEC 60947-2, magnetic tripping at 8 x In +/- 20 %, current limitation class 3 and full suitability for isolation. The A9F74320 clips onto 35 mm DIN rail, is 54 mm wide across six 9 mm pitches, takes up to 25 mm2 rigid copper at 2 N.m, and works from -35 to 70 degrees C at IP20. A 20 A C curve on three phases suits small motor feeders, pump and fan starters, packaging lines and HVAC circuits found in water treatment, food and beverage, cement and oil and gas facilities in Egypt and the GCC.
