The Siemens SENTRON 3VA1196-4ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release designed for line protection. Its interrupting capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC — numbers that matter for high-fault panels where upstream SCCR coordination is tight.
Breaking capacity and selectivity
At 415 V the breaker clears 75.6 kA, dropping to 52.5 kA at 440 V and 11.9 kA at 500/690 V. That 11.9 kA at 690 V is the limiting case for 690 V line-side applications — verify your available fault current against that number before committing the BOM. The TM210 release is thermal-magnetic, fixed-trip, no electronic adjustment or communication module. No undervoltage release, no ground-fault monitoring, no trip indicator — a straightforward line-protection device for distribution boards where selectivity is achieved by time-current curves, not electronics.
Thermal derating and panel fit
Rated 16 A from 40 °C through 55 °C; at 60 °C it derates to 15 A, holding at 15 A through 70 °C. That flat derating curve means the breaker can sit in a warm enclosure without losing much headroom — useful when the panel is packed and ambient runs high. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. That 76.2 mm width (3 inches) is a standard 3-pole MCCB footprint — fits most DIN-rail or backplate layouts without surprises. IP40 on the front, so it's fine for a clean indoor panel but not washdown areas.
