The Siemens 5SU1356-1DV06 is a combined residual-current device and miniature circuit breaker (RCBO) in a single 1+N-pole unit. The pig-tail connection simplifies wiring in distribution boards where neutral bars are pre-routed.
The 70 mm depth (D=70MM) fits standard flush-mount distribution boards. The pig-tail neutral connection is factory-fitted, so the installer connects only the phase line to the busbar and the pig-tail to the neutral bar — no additional neutral link wiring needed.
