The Siemens 5SU1356-0DA20 is a combined residual-current device and miniature circuit breaker (RCBO) — an FI/LS-protector — in a single module. The pig-tail neutral connection simplifies wiring in panel builds where the neutral bar is already landed.
Deployment context
Rated for DIN-rail mounting in a standard distribution board or sub-distribution panel. The 70 mm depth (D=70MM) fits enclosures with typical gland-plate clearance.
