The Siemens SENTRON 5SQ2370-0KA10 is a 3-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated at 10 A and 400 V AC, 50 Hz.
It does not switch the neutral conductor. Overvoltage category 3 and energy limiting class 3 mean it is designed for fixed-installation coordination — it limits let-through energy enough to protect downstream cabling and loads when a fault occurs within its 3 kA envelope.
3 kA per EN 60898 at 400 V AC. That is the standard residential and light-commercial fault level; verify it coordinates with the upstream protective device in your panel.
Yes — both are 3-pole, C-curve SENTRON 5SQ breakers with identical mechanical footprint (3 width units, 55 mm depth) and the same 400 V AC / 3 kA rating. The only difference is the current rating: 10 A on this part versus 4 A on the 2YA04. If the branch load is ≤10 A and the wiring and upstream protection are sized for 10 A, it is a direct mechanical swap.
