This delayed magnetic response is sized for loads with high inrush — motor starters, transformers, welding equipment — where a B- or C-curve would nuisance-trip on startup. The 4-pole configuration covers three-phase plus neutral, so it fits three-phase distribution panels feeding motor control centers or industrial machinery. Per the datasheet, the S800S series is designed for selective coordination in commercial and industrial switchboards.","metaTitle":"ABB S804S-D20 MCB S800S 4P D 20A, 50 kA","metaDescription":"ABB S804S-D20 MCB from S800S series, 4-pole, D-curve, 20 A, 50 kA interrupting capacity at 230 VAC.
