Breaking capacity is 4.5 kA per EN 60898 for residential infrastructure, with an IEC 60947-2 rating of 15 kA for industrial panel coordination. ## Temperature range and environmental fit Snaps onto standard DIN rail; supply can land on either top or bottom terminals — no forced orientation. IP20 rating applies once conductors are connected inside a distribution board. The 4 MW footprint means it occupies four 18 mm slots; plan derating when packing multiple RCBOs in a sealed enclosure.","metaTitle":"Siemens 5SU1323-1BB16 SENTRON RCBO, 16 A, 30 mA, C-Curve, 2P","metaDescription":"Siemens SENTRON 5SU1323-1BB16 RCBO, 2-pole, 16 A, 30 mA residual current, C characteristic, 4.5 kA per EN 60898.
