The 4-pole configuration (3 phases + neutral) suits three-phase distribution boards where neutral protection is required. The 50 kA interrupting rating at 230 V AC gives substantial fault-current headroom for industrial panelboards with high available short-circuit current.
Panel integration and deployment
The S800S footprint is wider than the S200 series; plan for 4-module width per pole on the DIN rail. Terminal capacity accepts up to 35 mm² conductor for the load side.
