Interrupting capacity hits 242 kA at 240 V and still holds 187 kA at 415 V and 440 V — that is high enough for most utility-grade fault levels downstream of a large transformer, and it drops to 121 kA at 500 V and 9 kA at 690 V, so on a 690 V system this breaker is not your main; it is a feeder or subfeed. The adjustable thermal-magnetic trip is set with an initial value of 126 A and a full-scale value of 630 A, and a trip indicator gives you a visual flag without opening the door — useful when you are panel-walking a faulted line and do not want to break the seal on every breaker. ## Environmental limits","metaTitle":"Siemens 3VA2463-6JQ32-0CH0 SENTRON MCCB, 630 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0CH0 molded case circuit breaker, 630 A at 40 °C, 3-pole, 242 kA at 240 V.
