The Siemens 5SL6020-6MF is a 1+N-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated at 20 A and 230 V AC with a 6 kA breaking capacity. It includes integral measuring and communication functions (RCM / EM Communication), meaning it reports status and current data back to the building management or panel controller — not just a passive overcurrent protector.
Compliance and regulatory notes
RoHS compliant since 30 April 2022. The description flags that radio approval is required in certain countries; the list of approved countries is in the Siemens certificates. No UL or CSA listing appears in the spec record — confirm with your Siemens partner for North American panel builds.
Mounts on standard DIN rail. The 1+N pole form factor fits a single module-width slot (18 mm wide per the packaging dimensions). The communication interface means it needs a data connection back to the controller — plan for a bus cable run, not just the power conductors.
