The Z-curve is designed for protection of sensitive electronic loads and semiconductor circuits where low inrush tolerance is required — it trips faster than a B- or C-curve on short-circuit but still allows for minimal overload margin. The 480Y/277 V rating means it is suitable for three-phase wye systems with line-to-neutral voltage of 277 V, common in North American commercial and industrial panels.","metaTitle":"ABB S203P-Z6 MCB 3P Z 6A 480Y/277, current lifecycle","metaDescription":"ABB S203P-Z6 miniature circuit breaker, 3-pole, Z-curve, 6 A, 480Y/277 V.
