The C characteristic means the magnetic trip operates at 5 to 10 times rated current (160–320 A for this 32 A unit), suited for circuits with moderate inrush — typical for motor starters, small transformers, or lighting banks in commercial panels. The Type A residual detection handles pulsating DC fault currents up to 6 mA smooth DC superimposed, covering single-phase rectified loads like switched-mode power supplies and LED drivers. The 100 mA sensitivity is a deliberate choice: it's above the 30 mA required for socket-outlet personal protection, so this unit is intended for equipment or submain protection where a higher trip threshold avoids nuisance tripping from leakage in longer cable runs or filtered supplies. ## Panel integration At 7 module widths (roughly 126 mm on a standard 18 mm/module DIN rail), this 4-pole RCBO fits a compact sub-distribution board. The neutral pole is switched and protected internally — no separate neutral bar needed downstream.","metaTitle":"Siemens 5SU1444-7RC32 RCBO 32 A 4-pole C curve Type A 100mA","metaDescription":"Siemens 5SU1444-7RC32 RCBO, 32 A, 4-pole, 7 modules, C characteristic, Type A, 100 mA residual.
