The Type B+ classification means it detects AC, pulsating DC, smooth DC, and high-frequency AC residual currents — covering VFD-fed loads, UPS systems, and EV charging circuits where pure sine-wave RCDs would be blind. The selective (S-type) design introduces a short intentional delay, so this unit coordinates downstream with standard RCCBs: on a fault, the nearest device trips first, keeping upstream circuits live. Mounts on DIN rail (REG) in any position, occupying 4 modular width units. The 70 mm depth matches standard distribution board cutouts. Rated short-circuit current withstand is 10 kA per IEC 61008-1, with a let-through current of 7 000 A and an I²t value of 60 000 A²·s — figures that matter when coordinating with an upstream MCB or fuse. The surge current resistance is rated at 5 kA (8/20 µs), covering lightning-induced transients common in industrial supply lines. The 80 A rating holds up to 45 °C ambient. Above that, derate linearly: 72 A at 55 °C, 64 A at 60 °C, 56 A at 65 °C, and 48 A at 70 °C. If the RCCB is enclosed in a non-ventilated panel, expect the internal temperature to run 10–15 °C above ambient — factor that into the effective current capacity. Silicon-free construction is noted for applications where silicone outgassing can contaminate contacts or optical surfaces — relevant in automotive paint shops or clean-room adjacent panels.","metaTitle":"Siemens SENTRON 5SV3647-5KK14 RCCB, 4P, 80 A, 300 mA, Type B","metaDescription":"Siemens SENTRON 5SV3647-5KK14 selective RCCB, 4-pole, 80 A rated, 300 mA residual, Type B+, 10 kA SCCR.

The 5SV3647-5KK14 offers broader fault detection (AC, pulsating DC, smooth DC, high-frequency) and intentional delay for selectivity — the 5SL4363-7 would trip faster but may not detect smooth DC or high-frequency residuals, and it cannot coordinate as an upstream device. Panel rewiring is not needed (same DIN-rail footprint, same pole count), but the protection characteristics differ significantly."},{"question":"What compliance documentation is available for the 5SV3647-5KK14?","answer":"The device is designed and tested to IEC 61008-1 (RCCB standard). As a Siemens SENTRON product, it carries CE marking for the European market. RoHS and REACH declarations are standard for current-production Siemens industrial controls — request these with your RFQ if needed for compliance files."},{"question":"How do I get pricing and availability for the 5SV3647-5KK14?","answer":"Submit an RFQ through this listing.
