The 4-module width (roughly 72 mm on a standard DIN rail) means it occupies four adjacent 18 mm positions in the consumer unit or distribution board — factor this into your fill plan, especially when grouping multiple RCBOs in a compact enclosure. D-curve coordination: upstream MCB or fuse must be sized to handle the let-through energy of a 40 A D-curve device at prospective short-circuit current; typical selectivity tables from the manufacturer should be consulted for the specific fault level at the installation point.","metaTitle":"5SU1324-2RC40 RCBO 40 A 2-pole D curve, 30 mA Type AC","metaDescription":"5SU1324-2RC40 RCBO, 40 A, 2-pole, D characteristic, 30 mA Type AC.
