Its interrupting capacity hits 220 kA at 240 V and holds at 154 kA at 415 V and 440 V, then drops to 121 kA at 500 V and 17 kA at 690 V — which means it handles high-fault utility feeds and large transformer secondaries without needing an upstream current-limiting fuse. ## Breaking Capacity and Selectivity — What the Ratings Mean At 415 V the 154 kA rating still covers most industrial switchboards. Minimum breaking capacity is 3 150 A and maximum is 5 040 A, defining the range over which the TM240 release operates within its calibrated curve. It is a straight line-protection device: thermal for overload, magnetic for short-circuit. The 630 A continuous rating holds flat from 40 °C through 50 °C, then derates to 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. No undervoltage release, no trip indicator, no voltage trigger — this is a bare-bones line-protection MCCB. If you need shunt trip or auxiliary contacts, those are separate add-on accessories for the 3VA platform.","metaTitle":"Siemens 3VA1463-6EF42-0AA0 SENTRON MCCB, 630 A, 4-Pole, 220","metaDescription":"Siemens 3VA1463-6EF42-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 4-pole, 220 kA interrupting at 240 V.
