The 20 A rating with a C characteristic means the device is designed to trip instantaneously at 5 to 10 times the rated current (100 to 200 A), which suits loads with moderate inrush, such as small motor circuits or lighting banks. ## Deployment Context The 2-module width (approx. 36 mm) means it fits alongside other modular devices in a row; plan for adequate heat dissipation when grouping multiple RCBOs — the manufacturer's derating guidelines apply above 40 °C ambient.","metaTitle":"Siemens 5SU1654-1RC20 RCBO, 20 A, 2-pole, Type AC 300 mA","metaDescription":"Siemens 5SU1654-1RC20 RCBO, 20 A, 2-pole, 2-module, C characteristic, Type AC 300 mA.
