The Siemens RC unit for 5SL4. It has a 4-pole and typeÂ. operating current 40 A and tripping residual current 30 mA. Supply voltage is 230 VAC.The RCD is the residual current device for touch protection. RCBOs (Residual current operated circuit breakers with overcurrent protection) combine residual current detection and overcurrent protection in a single device. The new 5SV1 RCBOs for the first time combine residual current and overload protection in one modular width (MW). This enables more protection devices to be installed in the distribution board and existing installations to be easily expanded with new protection functions in a space-saving solution. The protection devices can also be connected in a 5SM6 AFD unit - thus offering personal, line and preventive fire protection.

Protection class IP IP20 if the distribution board is installed, with connected conductors
