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.","metaTitle":"Siemens 3VA2340-6HN32-0CH0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens 3VA2340-6HN32-0CH0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, 242 kA breaking at 240 V.
