The Siemens SENTRON 3VA2140-6JP36-0AA0 is a 3-pole molded case circuit breaker rated for 40 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
Mounts into a SENTRON distribution panel or switchboard via the standard MCCB bolted connection — no DIN-rail adapter on this frame. The communication function allows integration with a higher-level monitoring system, useful for selective coordination logging or remote trip indication in a plant power distribution network.
With an insulation voltage rating of 800 V and interrupting capacity that drops from 242 kA at 240 V to 3.7 kA at 690 V, the 3VA2140-6JP36-0AA0 is primarily a low-voltage distribution breaker for 240–480 V services. The ETU550 release supports zone-selective interlocking (ZSI) when paired with a compatible upstream breaker, which speeds fault clearing on a downstream fault while maintaining full selectivity on a high-level fault. The 1.6 W maximum power loss is negligible for panel thermal budgeting.
