The Siemens 5SV1613-7KK10 is a compact RCBO (residual current circuit breaker with overcurrent protection) combining a 1P+N miniature circuit breaker and a Type A residual current device in a single 1-module-wide unit. The 4.5 kA breaking capacity at 230/400 V is sized for final sub-distribution in residential or light commercial panels where the prospective fault current stays below that threshold.
The 5SV1613-7KK10 is sourced to order through independent distribution channels. The product class is B (return restricted), so any order should be placed with the correct Siemens partner contact to avoid return complications.
