The Siemens 5SP4240-7 is a 2-pole miniature circuit breaker from the SENTRON 5SP4 family, rated 40 A at 400 V AC with a C tripping characteristic.
Installation depth is 70 mm, matching the standard SENTRON MCB footprint. Pollution degree 3 means the breaker is rated for conductive pollution environments typical of industrial control panels — no additional conformal coating required for normal factory atmospheres.
10 kA per EN 60898 and 20 kA per IEC 60947-2. The higher rating applies when the breaker is applied under the industrial standard, so check which standard your panel design references.
