At 690 V it still clears 3 kA, enough for most motor branch circuits on 690 V systems. ## ETU850 trip unit and selectivity This breaker carries the ETU850 electronic trip unit, which gives you adjustable long-time delay (tr) from 0.5 s to 25 s and a short-time delay (tsd) up to 0.5 s. The instantaneous pickup (Ii) is fixed at 10 times the rated current. In a distribution panel, those adjustable time bands let you coordinate downstream breakers — the 3VA holds in during a transient fault on a feeder, letting the branch breaker clear it first. That's selectivity without oversizing the main. ## Panel fit and communication It has a communication function onboard, which on this SENTRON platform typically means it can talk to a power monitoring system via a communication module (not included) for remote trip indication and current metering. Power loss is 5.4 W max — negligible for panel thermal calculations. The 5SQ2370-2YA05 is a functionally similar Siemens MCCB in the same SENTRON family, but it's an older generation with a different trip unit and no communication capability. The 3VA2063-6KP36-0AA0 replaces it in new designs — same 3-pole 63 A frame, but with the ETU850 electronic trip and communication interface. If you're swapping out a 5SQ2370-2YA05 in an existing panel, check the mounting hole pattern and bus bar spacing; the 3VA shares the same 105 mm width and 86 mm depth, so it should drop in without rewiring, but verify the lug kit compatibility. The interrupting ratings on the 3VA are higher across the board.","metaTitle":"Siemens 3VA2063-6KP36-0AA0 SENTRON MCCB, 63A, 242kA at 240V","metaDescription":"Siemens SENTRON 3VA2063-6KP36-0AA0 molded case circuit breaker, 63A continuous, 242kA at 240V. 3-pole, ETU850 release.
