ABB SU203M-C40 is a 3-pole miniature circuit breaker from the S200M family, rated for 40 A with a C-type tripping characteristic, designed to provide branch-circuit protection in low-voltage AC distributions. It is UL489-listed and intended to interrupt fault currents in three-phase electrical systems, helping protect conductors and connected equipment. This 40 A, C-curve variant fits ABB’s SU200M/S200M line for standard three-phase protection in commercial and light-industrial installations.
