The interrupting ratings are the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V — that 242 kA figure at 240 V tells you this breaker is sized for high-fault-capacity main feeders or large sub-distribution boards where the available fault current is serious. The 63 A rating holds flat from 40 °C to 50 °C, then derates stepwise to 53.55 A at 70 °C; if your panel ambient runs hot, that's the real continuous current you can count on. ## What the ETU350 and auxiliary options mean for your BOM The shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit. The auxiliary contact block includes a trip alarm switch and an electrical alarm switch, so you can signal both a normal open/closed status and a trip event back to the control system. No communication function, no phase-failure detection, no undervoltage release on this order code — if you need those, this isn't the variant.","metaTitle":"Siemens 3VA2063-6HN32-0KL0 SENTRON MCCB, 63 A, 3-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2063-6HN32-0KL0 molded case circuit breaker, 63 A, 3-pole, 242 kA at 240 V.
