It's rated 16 A with a C-curve tripping characteristic, 30 mA type A residual-current sensitivity, and a 10 kA breaking capacity per EN 60898 and IEC 60947-2. The supply can enter from either top or bottom, and the unit includes a 600 mm pigtail for the neutral connection. The 30 mA type A residual-current element detects both sinusoidal AC faults and pulsating DC faults, which covers most modern electronics and variable-speed drives downstream. The 1P+N design protects only the phase conductor; the neutral is switched but not protected. The solid N pigtail simplifies wiring in distribution boards — the neutral bar connection is factory-terminated, reducing installation time. At 18 mm width and 77 mm depth, it occupies a single modular unit on a DIN rail. The IP20 rating is standard for enclosed distribution boards — the protection is only complete once the board cover is fitted and conductors are connected.","metaTitle":"Siemens 5SU9304-7KK16 SENTRON RCBO, 16 A, 30 mA, C-Curve, 10","metaDescription":"Siemens 5SU9304-7KK16 SENTRON RCBO, 1P+N, type A, 30 mA, C-curve, 16 A, 10 kA breaking capacity per EN 60898.

The 5SU9304-7KK16 is a type A, 30 mA, C-curve, 16 A unit with a solid N pigtail; the 5SL6120-7 is a different variant. Check the rating and residual-current type against your circuit design — the mechanical fit is the same, but the electrical specification must match."},{"question":"What compliance documentation does Siemens provide for 5SU9304-7KK16?","answer":"The part carries ratings per EN 60898 and IEC 60947-2, which implies CE marking for the European market.
