SENTRON 3VA1196-3ED36-0AA0 — MCCB for Line Protection
It carries a TM210 thermal-magnetic release — the '210' designates a fixed thermal element with an adjustable magnetic trip up to 320 A. That adjustable short-circuit pickup is the key setting for coordination studies: you can dial the magnetic threshold to ride through motor inrush or transformer magnetizing current without nuisance tripping. Breaking capacity varies sharply with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating is flat to 55 °C (still 16 A), then drops to 15 A at 60 °C and holds there through 70 °C. That's a forgiving curve for a warm panel — you don't lose headroom until the ambient passes 55 °C. Power dissipation is 10.6 W maximum, which matters for enclosure thermal calculations when grouping several breakers.
Dimensions & Panel Fit
The 3VA1196-3ED36-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB footprint that fits standard Siemens SENTRON 3VA panel cutouts and busbar systems. Front IP40 is typical for enclosed distribution boards; no special sealing required for dry indoor locations.
DC Capability & Options
Maximum rated operational voltage on DC is 500 V — the breaker can be used in DC distribution or battery circuits up to that voltage, though the manufacturer directs you to the 3VA device manual for DC switching power values. The breaker accepts an optional motor drive (external operator) for remote tripping or reset, and the adjustable magnetic trip (Ii max 320 A) gives flexibility for non-standard loads.
