Occupies 4 modular width units at 60 mm grid spacing — 72 mm wide, 90 mm tall, 70 mm deep. Rated at 50 Hz only (not 50/60 Hz dual-frequency). Overvoltage category III — suitable for fixed-installation distribution boards, not for downstream equipment-side protection. The device is silicon-free — relevant for automotive or electronics manufacturing environments where silicone outgassing can contaminate contact surfaces or optical assemblies. Designed and tested according to IEC 61008-1 (residual current operated circuit-breakers without integral overcurrent protection for household and similar uses). The rated conditional short-circuit current per IEC 61008-1 is 0.8 kA (the lower value reflects the standard's test condition for the RCCB itself; the device's own SCCR of 10 kA is the withstand rating when backed by an appropriate upstream overcurrent protective device — the maximum permissible series fuse is 80 A). Supplementary devices can be installed (e.g., auxiliary switches or shunt trips). No UL, CSA, or UKCA listing is stated in the evidence; for North American or UK installations, verify local acceptance before specifying.","metaTitle":"Siemens 5SV3644-6BA SENTRON RCCB, 4-pole Type A, 40 A, 300 m","metaDescription":"Siemens SENTRON 5SV3644-6BA 4-pole RCCB, type A, rated 40 A / 300 mA at 230/400 V AC, 10 kA SCCR.
