Trip curve and selectivity
Curve C trips magnetically between 5 and 10 times rated current (160–320 A for this 32 A unit). That makes it a standard choice for general-purpose distribution where inrush from small motors, transformers, or lighting ballasts stays below the magnetic threshold. For a panel feeding a mix of resistive and moderate inductive loads, Curve C gives a clean selectivity window downstream of a higher-rated upstream device.
