Mounts on DIN rail (REG) and fits into a 4-module-width grid (60 mm spacing). The 300 mA sensitivity is sized for equipment protection (fire prevention) rather than personal shock protection, which typically requires 30 mA or lower. The 63 A continuous rating matches the upstream feed; verify that the load current stays under this at 400 V three-phase. Rated for 50 Hz only (not 50/60 Hz), so confirm the line frequency matches before specifying. The 70 mm depth matches the typical SENTRON RCCB/MCB family, so it sits flush in a distribution board alongside 5SL or 5SY breakers. The IP20 rating applies only when the distribution board is installed with connected conductors; plan for proper enclosure sealing if the board is in a dusty or wet area.","metaTitle":"Siemens SENTRON 5SV4646-0 RCCB, 4-pole, 63 A, 300 mA","metaDescription":"Siemens 5SV4646-0 SENTRON RCCB, 4-pole, Type AC, 63 A, 300 mA, 400 V AC, 10 kA SCCR, IP20.

The 5SV4646-0 is 72 mm wide (4 module widths) versus 54 mm (3 modules) for the 5SL4363-7, so it needs one extra module space.
