The Z curve is designed for protection of electronic loads and semiconductor circuits where inrush is minimal and a tighter overload band is needed than a B or C curve provides. Snap-on mounting to standard DIN rail. The 3-pole footprint occupies three modular units (each 17.5 mm wide) on the rail, matching the System pro M compact family layout for panel integration.","metaTitle":"ABB S203-Z6 3P Z 6A 480Y/277 Din Rail Circuit Breaker","metaDescription":"ABB S203-Z6 3-pole Z-curve 6A miniature circuit breaker, 480Y/277 VAC.
