The ABB 2CSR275180R1164 is a 2-pole RCBO rated at 16 A with C-curve tripping, designed for DIN rail mounting. It provides overcurrent and earth leakage protection in one compact 35 mm wide package. The C characteristic handles moderate inrush loads common in industrial control panels and commercial distribution. Service breaking capacity Icn is 10 kA; ultimate breaking capacity Icu is 15 kA. The higher Icu rating means the device can interrupt a fault current exceeding the service rating without damage, a useful margin for high-fault installations. Bi-directional cylinder lift terminals, tighten to 2.8 Nm. IP20/IP40 rating.
