Product details

The 5SP9210-7KC47 is a 2-pole miniature circuit breaker from the Siemens SENTRON 5SP9 series, rated 10 A with a C tripping characteristic. The 50 kA breaking capacity per IEC 60947-2 means it can safely interrupt fault currents up to 50 kA at 400 V AC — high enough for most industrial panelboard applications where the prospective short-circuit current is substantial.

Occupies 3 width units (approx 54 mm) on the rail. Tunnel terminals top and bottom accept solid or stranded conductors from 0.75 to 50 mm² (AWG 14 to 2). Tightening torque 2.5 to 3.5 N·m (22 to 31 lbf·in).

Frequently asked questions

What is the breaking capacity of the 5SP9210-7KC47?

50 kA per IEC 60947-2 at 400 V AC. This is the maximum fault current the breaker can safely interrupt under standard test conditions.

What conductor sizes does the 5SP9210-7KC47 accept?

Solid and stranded conductors from 0.75 to 50 mm² (AWG 14 to 2). The tunnel terminals are sealable and accept both copper and aluminum if rated for the application.

Where can I buy the 5SP9210-7KC47?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
