This ABB 2CSR256140R1164 is a 4-pole RCBO rated 16 A with C-trip characteristics—suited for final circuits feeding lighting or motor loads where moderate inrush current is typical. The 6 kA Icn (service breaking capacity) defines the routine short-circuit capability for coordination studies; the 10 kA Icu (ultimate breaking capacity) indicates the device can clear one major fault and remain functional, though replacement after a fault is standard practice. The 4-pole configuration covers three phases plus switched neutral, matching 3P+N distribution. Rated at 50 Hz only—verify system frequency before specifying. DIN-rail mount simplifies panel assembly. Depth of 69 mm, width 71 mm, height 85 mm—standard modular footprint.
