Product details

Interrupting Capacity and Trip Curve

The 5SJ4240-7HG41 is a 2-pole miniature circuit breaker from the Siemens SENTRON 5SJ4 series, carrying dual interrupting ratings: 10 kA per EN 60898 and 15 kA per IEC 60947-2. For a 400 VAC line, that 15 kA IEC rating gives the SCCR headroom to coordinate downstream of a larger feeder breaker without cascading.

Environmental and Application Range

Vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz means it stays latched on a conveyor line or pump skid.
