Three poles, fitted with the ETU550 electronic trip unit. The ETU550 is a microprocessor-based overcurrent release with adjustable time-current curves — tr adjustable from 0.5 s to 25 s, tsd up to 0.5 s — giving you selective coordination flexibility downstream of a transformer or upstream of distribution panels. Breaking capacity is voltage-dependent: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. That puts it in the high-interrupting category for this frame size — suitable for fault currents near the transformer secondary in industrial switchgear. The 3VA2 frame uses a screw-fixed mounting pattern — not DIN rail — so plan for a drilled backplate or mounting plate in the enclosure.","metaTitle":"Siemens 3VA2140-8JP32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens 3VA2140-8JP32-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, ETU550 electronic trip unit, 440 kA at 240 V.
