RCBO for branch-circuit protection and personnel protection
The Siemens 5SU9304-7KX10 is a combined residual-current circuit breaker (RCBO) in the 5SU9 family, integrating overcurrent and earth-fault protection into a single 1P+N module. The 600 mm pigtail and solid neutral simplify wiring in distribution boards where the neutral bar is remote from the device.
The product class is B (return restricted), so direct returns to Siemens are limited; coordinate with your supply partner on any disposition needs.
