The Icn of 10 kA is the service rating for repeated operation: your supply-side SCCR needs to stay below that for the panel's fault-withstand rating. Overvoltage category III means it's rated for fixed-installation distribution boards, not for socket-outlet circuits. The IP20 front and IP40 housing keep dust out of the enclosure but don't rely on it wet. Terminal torque spec of 2.8 Nm — standard for this class. Use a torque screwdriver on the cylinder-lift terminals; overtightening strips the clamp.","metaTitle":"ABB 2CDS273103R0164 MCB, 4P C 16A, 25kA","metaDescription":"Active-production ABB miniature circuit breaker, 4-pole C-curve 16 A, 440 V insulation, 25 kA Icu, IP20/IP40, DIN rail mount.
