At 415 V it clears 121 kA, same at 440 V. That drops to 75.6 kA at 500 V and 11.9 kA at 690 V.
No ground-fault monitoring module is included; if you need GF protection, that's a separate accessory. The trip indicator is not fitted, so you won't get a visual flag on the front — factor that into your panel inspection routine.
As a Siemens SENTRON MCCB, it carries UL, CSA, and IEC certifications. RoHS and REACH declarations are available from the manufacturer. The specific approvals for this order code should be confirmed at order time.
No — the 3VA1332 frame is physically smaller (248 x 184 x 110 mm) than the 3VA2225 frame, and the mounting hole pattern differs. You would need to verify the panel cutout and busbar spacing before substituting.
