The 70 mm width fits standard Siemens distribution board cutouts. The 300 mA residual-current sensitivity (Type A) detects pulsating DC fault currents, which standard AC-only RCDs miss; this is required for circuits with single-phase rectifiers, switched-mode power supplies, or variable-speed drives. ## Panel integration The 70 mm module width (4.5 standard DIN modules) snaps onto a DIN rail in the distribution board. The 1+N-pole design switches the line conductor only; the neutral is switched internally for isolation but not protected against overcurrent.","metaTitle":"Siemens 5SU1656-7KV32 FI/LS-Protector, Type A, 6kA, 32A C-cu","metaDescription":"Siemens 5SU1656-7KV32 FI/LS-Protector Type A, 300mA, 6kA, 1+N-pole C 32A.
