The Siemens 3VA1196-6GD42-0AA0 is a SENTRON 4-pole molded case circuit breaker (MCCB) rated for 16 A continuous current. Its interrupting capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V — numbers that matter when you're protecting a high-fault panel feeding a transformer or a large motor branch. The TM210 thermal-magnetic release handles overload and short-circuit protection without a separate relay.
DIN-rail footprint and panel fit
At 70 mm deep, 101.6 mm wide, and 130 mm tall, this MCCB fits standard panel-mount cutouts for 4-pole breakers in the 16 A class. The IP40 front protection means it's sealed against tools and fingers but not washdown — keep it inside a cabinet, not on the open line.
Current derating and thermal limits
Rated continuous current holds at 16 A from 40 °C up to 55 °C, then derates to 15 A at 60 °C and 65 °C, and stays at 15 A up to 70 °C. That's a flat thermal curve — no surprise drop at 50 °C, which simplifies panel sizing in warm cabinets. Maximum power loss is 10.6 W.
Lifecycle and sourcing
Listed as current production. The 3VA1196-6GD42-0AA0 is a line-protection variant with no communication module and no ground-fault monitoring — a straight thermal-magnetic MCCB for standard distribution. Quoted to order against an RFQ; availability and current pricing confirmed at quote time.
