The Siemens SENTRON 5SL6604-7 is a 4-pole miniature circuit breaker (3P+N) with a C tripping characteristic, rated 4 A at 400 V AC. The C-curve means it holds through moderate inrush (e.g., small motor or transformer loads) and trips fast on a hard short.
The neutral is switched (3P+N), so it disconnects all live conductors on a fault.
Current-production status. No end-of-life notice on record.
The depth is 76 mm, with an installation depth of 70 mm. Width is 72 mm (4 modular units), height 90 mm.
Both are 4-pole SENTRON MCBs with the same DIN-rail footprint and 4-module width. The 5SL6604-7 is a 4 A C-curve; the 5SL3640-7MB is a different rating/curve — verify the branch-circuit protection requirements before swapping. No wiring change needed if the rating matches the design.
