Product details

Siemens 5SN6220-7CP — 2-Pole MCB for 400 V AC Circuits

The Siemens 5SN6220-7CP is a 2-pole miniature circuit breaker from the SENTRON 5SN series, rated for 400 V AC at 50 Hz. It carries a 6 kA breaking capacity per EN 60898 for residential/commercial branch circuits, and a 15 kA rating per IEC 60947-2 for industrial panel applications — meaning it can safely interrupt fault currents up to 15 kA in an industrial distribution board without upstream cascading.

Panel Fit and DIN-Rail Integration

Solid conductors up to 35 mm² can be terminated directly.

Frequently asked questions

Will 5SN6220-7CP drop into a panel specified around 5SU9354-7KK16 without rewiring?

Both are 2-pole, 36 mm wide, 70 mm installation depth, and mount on standard DIN rail. The 5SU9354-7KK16 is an RCBO (RCD + MCB combo), while the 5SN6220-7CP is a plain MCB — so the wiring differs if RCD protection is required, but the physical footprint and rail position are identical.
