The Type B+ characteristic means it detects AC, pulsating DC, smooth DC, and high-frequency AC residual currents — covering variable-speed drives, UPS systems, and PV inverters that generate mixed-frequency leakage. The selective (S-type) design introduces a short intentional delay so the downstream RCCB trips first, keeping this unit as the back-up for discrimination in a multi-level distribution board. The 10 kA short-circuit current rating matches the fault level typical of a main distribution panel; the 0.8 kA rated conditional short-circuit current per IEC 61008-1 confirms the device withstands that fault without damage when protected by a series fuse up to 100 A. Snap-on DIN-rail mounting in any orientation — installs in a standard 60 mm grid distribution board. Occupies 4 modular width units at 72 mm wide. Depth of 70 mm fits standard 70 mm installation depth enclosures. Silicon-free construction for applications sensitive to silicone outgassing (e.g., in proximity to coating or bonding lines).","metaTitle":"Siemens 5SV3646-5KK14 SENTRON RCCB, 4-pole, 63 A, 300 mA, Ty","metaDescription":"Siemens SENTRON 5SV3646-5KK14 RCCB, 4-pole, Type B+, selective, 63 A, 300 mA, 400 V AC.
