Schneider Acti9 iK60N A9K24320 3P 20A C-Curve 6kA MCB
Submit your RFQ. Our team will send a quotation confirming price and availability.
Schneider Electric A9K24320 is an Acti9 iK60N three-pole miniature circuit breaker rated 20A at 30°C. Its C-curve thermal-magnetic trip protects all three poles against overload and short circuit, with 6kA Icn and 6kA Ics at 400VAC under EN/IEC 60898-1. The 54mm-wide device clips onto 35mm DIN rail and accepts top or bottom feeding. It does not provide earth-leakage protection.
