This is a SIEMENS SENTRON residual current circuit breaker (FI), model 5SM3346-6KL.

It's a Type A, with a rated current of 63A and a trip sensitivity of 30mA (0.03A).
It has 4 poles and is rated for 230-400V AC.

It's designed for DIN rail mounting, with screw terminals.
The neutral connection is on the left.

It's IP20 rated, measures 90mm high, 72mm wide, and 64mm deep.

This one is used, but the seller notes it's from a liquidation of unused gear—it was removed from a system that was never actually put into service.
So there might be light installation marks, but it's essentially new old stock.
Made in Germany.

No EAN.

Solid, reliable SIEMENS quality for your electrical panel.
