Siemens 3VA1080-3ED42-0AA0 — 80 A SENTRON MCCB for Line Protection
The 4-pole configuration suits three-phase-plus-neutral or dual-feed applications where full isolation is required.
Interrupting ratings climb to 75.6 kA at 240 V and hold 52.5 kA at 415 V, which gives solid selectivity headroom downstream of a larger main breaker or transformer secondary. At 440 V it still clears 32 kA, and at 500 V or 690 V it holds 7.5 kA — enough for most industrial motor-control centres on a 480Y/277 V service. The TM210 overcurrent release combines a thermal-magnetic trip with fixed time-current characteristics; no electronic adjustments, so the curve is repeatable across units in a multi-source BOM.
Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB envelope that drops into most SENTRON or third-party distribution blocks without re-drilling the gland plate.
