If your panel runs hot, size the load accordingly or you'll nuisance-trip on the thermal element. The 30 mA residual-current trip is the standard for personal protection in most residential and commercial circuits. If your load includes VFDs, UPS gear, or LED drivers that can generate DC fault components, you need a type A or F RCBO instead. The design is instantaneous (no intentional time delay on the residual element), so it trips fast on a ground fault. Installed depth is 77 mm, overall height 125 mm. Keep it inside a dry enclosure. The part also carries energy limitation class 3, meaning it limits let-through energy well enough to coordinate with downstream equipment in most cases.","metaTitle":"Siemens 5SU9304-1KK16 SENTRON RCBO, 16 A, 30 mA, 10 kA","metaDescription":"Siemens SENTRON 5SU9304-1KK16 RCBO, 1P+N, 16 A, 30 mA residual, 10 kA breaking capacity.

Submit a request for quote (RFQ) with your quantity and delivery target; we confirm current pricing and availability at quote time."},{"question":"What is 5SU9304-1KK16's listed depth (77 mm) on this component line?","answer":"The installed depth is 77 mm, with an overall height of 125 mm and width of 18 mm (one modular unit). Make sure your enclosure has at least 77 mm of clear depth behind the DIN rail."},{"question":"Will 5SU9304-1KK16 drop into a panel that was specified around 5SY4116-6CC without rewiring?","answer":"Both are 1P+N, 16 A, 30 mA, type C RCBOs in 18 mm width — so the footprint and electrical ratings are the same. The 5SU9304-1KK16 is the SENTRON version; the 5SY4116-6CC is a different series. Check terminal type and wire range before swapping, but in most standard panels it will fit without rewiring."},{"question":"What compliance documentation does this brand provide for 5SU9304-1KK16 (RoHS, REACH, UL, IEC)?","answer":"The part is rated per EN 60898 and IEC 60947-2, and carries overvoltage category III and pollution degree 2.
