The SENTRON 5SM9325-0KK is a 2-pole electronic residual current unit (RC unit) rated for 40 A at 400 V AC, with a 30 mA trip threshold and type AC sensitivity. It's an instantaneous design, meaning it trips without a time delay — suited for general-purpose fault protection where selectivity with upstream devices isn't required.
In a crowded DIN-rail enclosure with multiple heat sources, use the 50 °C figure (36 A) as your practical continuous limit.
It is rated at 40 A with a 30 mA residual trip current, type AC, at 400 V AC, 50 Hz.

No — the 5SQ2570-2YA04 is a 4 A miniature circuit breaker (MCB) with C-curve trip characteristic, not an RC unit. The 5SM9325-0KK is a 40 A residual current device with a different function, footprint, and wiring scheme. They are not drop-in replacements.
