Summary:The invention relates to a spring drive cam (3) for a spring drive (1) of a circuit breaker (2) comprising a disc-like shape configured for rotating around a rotation axis (11) in the spring drive (1), whereby the disc-like shape comprises a radius (R) that changes depending on an angle (α) of the radius (R) relative to a base angle (α0), and whereby a rate (dR/dα) defined by a change of the radius (R) per change of the angle (α) is ≤ 0,3 mm/°.
