Type A residual detection catches pulsating DC fault currents, not just sinusoidal AC, so it covers half-wave rectified loads like switching power supplies and variable-speed drives. At 7 module widths (roughly 126 mm on a standard 18 mm/module DIN rail), it fits a standard distribution board or sub-panel. The C characteristic and 63 A rating make it suitable for final subcircuits supplying mixed resistive and inductive loads up to that current. The 300 mA Type A residual element provides earth-fault protection for equipment that generates pulsed DC fault currents — common in modern panels with electronic loads.","metaTitle":"Siemens 5SU1644-7RC63 RCBO, 63 A 4-pole C Type A 300mA","metaDescription":"Siemens 5SU1644-7RC63 RCBO, 63 A, 4-pole, 7 modules, C characteristic, Type A, 300 mA residual.
