SENTRON 3VA1096-3ED32-0AD0 — 16 A MCCB with TM210 release
The Siemens SENTRON 3VA1096-3ED32-0AD0 is a 3-pole molded case circuit breaker rated for 16 A continuous current, carrying a TM210 thermal-magnetic release for line protection duty. Its interrupting capacity is rated across four voltage levels: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — so it can be applied in 400 V class distribution without worrying about fault current escalation upstream. The TM210 release is a fixed thermal-magnetic design — no adjustable trip settings, which simplifies specification but means it must be sized precisely to the load. Rated insulation voltage is 800 V, so it can be used in 690 V systems where the insulation class is the binding constraint.
Temperature derating and panel integration
The 3VA1096-3ED32-0AD0 carries 16 A from 40 °C through 50 °C without derating. Above that, current must be reduced: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C. In a sealed panel with internal heat rise, the 55 °C column is the realistic operating point for most industrial enclosures — plan for 15.36 A continuous, not the 16 A nameplate. Footprint is 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA frame that fits the DIN-rail mounting grid. Front protection is IP40, so it is suited for panel interiors but not for washdown zones or outdoor cabinets without an additional enclosure. Operating temperature range spans -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The storage limit governs handling and warehousing, not running conditions.
Auxiliary contacts and lifecycle
This variant ships with three HQ auxiliary switches integrated — no separate aux contact block to order. The auxiliary contact version is stated as 3 auxiliary switches HQ, which provides status feedback for the main contacts without adding wiring layers. Mechanical endurance is rated at 15,000 operations (latching endurance). For a line-protection MCCB that cycles infrequently — typically fewer than a few hundred operations per year — this is adequate. It is not designed for frequent switching duty like a contactor. The product lifecycle stage is listed as current production. No phase-out or last-time-buy notice is indicated for this order code.
