The 2CDS273103R0164: The Icu of 25 kA at 440 V tells you this breaker clears a hard short without welding contacts — it's the fault current it can interrupt once. 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.

Frequently asked questions
What is the breaking capacity of ABB 2CDS273103R0164 at 440V?
Buyers need confirmed Icu/Ics kAIC at the system voltage to validate short-circuit coordination before purchase.
Is the ABB S200M 4P C16 25kA MCB certified to IEC 60898 or IEC 60947-2?
Standard applicability dictates whether the MCB qualifies for residential (60898) or industrial (60947-2) installations.
What auxiliary and signal contact blocks fit the ABB 2CDS273103R0164?
Panel builders must confirm accessory part numbers to avoid catalog ambiguity and ordering errors.
How do I identify a genuine vs counterfeit ABB 2CDS273103R0164?
Premium allocated ABB MCBs carry counterfeit risk; trace and COA signals are decisive for procurement trust.
What is the current lifecycle status of ABB 2CDS273103R0164 and is there a replacement?
Obsolete/LTB managers and MRO buyers need PCN status and qualified FFF alternates to plan spares and migration.
What are the torque settings and DIN rail dimensions for the ABB 2CDS273103R0164?
Installers need verified torque and footprint data to assemble panels to spec without rework.
