The Siemens 3VA1196-6ED32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C with a TM210 thermal-magnetic overcurrent release, designed for line protection in three-phase distribution panels. Its interrupting capacity reaches 220 kA at 240 V — that is the headline number for fault duty at the lowest common distribution voltage, meaning it can clear a bolted fault up to that level without rupturing or cascading to upstream gear. At 415 V the rating drops to 154 kA, at 440 V to 121 kA, and at 500 V or 690 V it holds at 17 kA — the steep fall-off above 440 V is typical of a compact MCCB frame and matters if your secondary is a 480 V or 600 V class transformer. The TM210 release is a fixed thermal-magnetic design — no electronic trip unit, no communication module, no ground-fault monitoring. That keeps the BOM simple and the part interchangeable with older panels that expect a non-electronic MCCB.
Lifecycle and sourcing posture
No official successor order code has been published for this part; the 3VA1 platform remains the current SENTRON MCCB generation for line-protection applications.
Dimensions and panel fit
The 3VA1196-6ED32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB footprint that drops into standard SENTRON 3VA1 mounting bases and busbar systems. Front-face protection class is IP40, which is typical for a panel-mounted MCCB — no special gasketing needed for dry indoor enclosures, but not rated for washdown or outdoor exposure. Maximum power dissipation is 10.6 W — negligible for thermal budgeting in a standard distribution panel, but worth noting if the MCCB is densely packed with other heat sources in a sealed enclosure.
Ambient derating and operating range
The 16 A rating holds flat from 40 °C through 55 °C; at 60 °C it derates to 15 A and stays there through 70 °C. That means no capacity loss in most ventilated panels, but a sealed enclosure near other heat sources may push the effective rating down. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage minimum is the more restrictive number for warehousing — keep it above -40 °C and the breaker will not suffer mechanical damage before installation.
