The Siemens 5SN6410-7CP is a 4-pole miniature circuit breaker from the SENTRON 5SN series, rated at 400 V AC and 50 Hz. It carries a 6 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2, meaning it can safely interrupt fault currents up to those levels in a residential or light commercial distribution board — the higher IEC figure applies when the breaker is used in industrial coordination schemes per 60947-2.
The 5SN6410-7CP measures 72 mm wide by 90 mm high by 76 mm deep, with an installation depth of 70 mm. At 4 modular width units, it occupies four slots on a standard DIN rail.
Rated for multi-phase and single-phase operation at 440 V AC maximum, and 72 V DC maximum.
Environmental range and conductor sizing
The solid conductor terminal accepts up to 35 mm².
