At 415 V and 440 V it still interrupts 242 kA; at 690 V it holds 52.5 kA. The auxiliary contact version is 2 auxiliary switches HP, enough to signal the breaker position back to a PLC or status lamp without an add-on module. The 630 A rating holds only at 40 °C. At 50 °C it derates to 593 A; at 60 °C to 557 A; at 70 °C to 520 A. Maximum power loss is 162 W, which contributes to the enclosure's thermal budget. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. The ETU320 is powered by integral current transformers; no external control power needed for the trip unit.","metaTitle":"Siemens 3VA2463-7HL32-0AB0 SENTRON MCCB, 630 A, 330 kA","metaDescription":"Siemens SENTRON 3VA2463-7HL32-0AB0 molded case circuit breaker, 630 A rated at 40 °C, 330 kA breaking at 240 V, ETU320 trip unit, 3-pole, IP40 front.
