Siemens 3VA1196-3ED12-0AA0 — 1-Pole 16 A SENTRON MCCB, TM210 Release
The Siemens 3VA1196-3ED12-0AA0 is a SENTRON molded case circuit breaker (MCCB) in a 1-pole form factor, rated 16 A at 40 °C with a TM210 thermal-magnetic overcurrent release. Its interrupting capacity hits 52.5 kA at 240 V AC and 7.5 kA at 415 V AC, making it a solid choice for line protection in distribution panels where high fault current is a concern.
Rated current holds at 16 A from 40 °C through 55 °C, then derates to 15 A at 60 °C through 70 °C. That flat thermal curve means you don't lose headroom until the ambient inside the enclosure pushes past 55 °C — useful when the MCCB shares a crowded DIN rail with other heat sources. Breaking capacity of 52.5 kA at 240 V AC covers most North American 120/240 V split-phase service entrance requirements. At 415 V AC (common in European 400 V three-phase systems), it still clears 7.5 kA — adequate for downstream sub-distribution but not for high-fault main breakers. The 125 V DC rating (operating voltage) opens the door for DC control circuits or battery-backed loads. Physical footprint: 25.4 mm wide (1 inch), 130 mm tall, 70 mm deep. That 1-pole width matches standard DIN-rail modular breaker spacing — it clips onto the rail and occupies one module position.
The 3VA1196-3ED12-0AA0 carries RoHS, REACH, and CE marking. The device manual is available under Service & Support on Siemens' site.
