Interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Compared to the 3VA1110-5EF32-0AM0, this 3VA2163 frame is physically larger (105 mm wide vs the 1110's 70 mm) and carries higher interrupting ratings. The 1110 tops out at 36 kA at 415 V; this unit delivers 121 kA at the same voltage. If the panel was specced around the 3VA1110-5EF32-0AM0, the 3VA2163-5HL32-0CL0 will not drop in without rewiring — different footprint, different bus connections.
The UVR drops the breaker on loss of control voltage — standard for safety circuits where a downstream contactor or safety relay needs to force a trip. The auxiliary switch set provides status feedback for PLC or SCADA inputs without adding external relays.
