The 3VA2340-6HN32-0CH0: Breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. Those are the ultimate short-circuit breaking capacities (Icu) — the numbers you need for fault-level coordination studies. At 415 V, 187 kA gives you headroom for most industrial transformer-fed busways; the 7.5 kA at 690 V is notably lower, so if this breaker feeds a 690 V drive or motor circuit, verify the prospective fault current at that voltage doesn't exceed that figure.
The UVR means the breaker trips on loss of control voltage — standard for safety circuits where a drop in the control supply should open the main power. The auxiliary switch complement gives you status feedback for both the main contacts and the trip condition without adding external interposing relays.
