Selection Notes
ABB's own verified rating data for this catalog number lists a 3800 A conventional thermal current, not the 4000 A the OT4000E04P designation implies — confirm the current duty against the installation's calculated load before specifying it as a 4000 A device. Its 80 kA Icw and 176 kA Icm are the highest in the OT switch-disconnector range covered here, reflecting the fault levels expected near a large main incomer.
