The Type A designation means it detects pulsating DC residual currents in addition to sinusoidal AC — a requirement for circuits with single-phase rectifiers, switched-mode power supplies, or VFDs that generate pulsed DC fault currents. The 30 mA rating covers personnel protection (indirect contact) per IEC 60364. Lifecycle stage is listed as current — meaning Siemens still produces this order code. No phase-out or last-time-buy notice is on record.","metaTitle":"Siemens 5SM1347-6BA FI Protector Type A, 80A 4P 30mA 400V","metaDescription":"Siemens 5SM1347-6BA FI protector Type A (PSE/SSF), 80A 4-pole, 30mA residual current, 400V.
