The Siemens 5SL6025-7MF is a 1+N pole miniature circuit breaker (MCB) with a C-curve trip characteristic, rated 25 A, and a 6 kA breaking capacity at AC 230 V. It includes integrated RCM (Residual Current Monitoring) and EM (Energy Management) communication capability, which means it can report status and energy data to a building management or industrial control system — not just a passive overcurrent protector but a communicating device for branch-circuit monitoring. Because this is a 1+N pole device, it switches both the line and neutral conductors, with overcurrent protection only on the line pole. The neutral pole is a switching-only pole, which meets the requirements of many regional wiring regulations for single-phase final subcircuits.
Compliance and regulatory notes
The product requires radio approval for the RCM/EM communication function. The list of approved countries is provided in the Siemens certificates — verify your jurisdiction before specifying the communication feature.
Panel integration
Packaged as a single piece, dimensions 90 x 18 x 80 mm — a standard 1-module (18 mm per pole) DIN-rail footprint. The 1+N configuration occupies 2 module widths (36 mm) on the rail.
