This SENTRON 3VA4195-4ED34-0AA0 is a 3-pole molded-case circuit breaker (MCCB) rated 15 A at 40 °C, with a TM210 thermal-magnetic release. The interrupting capacity hits 65 kA at 240 V AC and 25 kA at 480 V AC — enough to handle most industrial panel fault currents without cascading upstream breakers.
What the ratings mean on the line
The 15 A rating at 40 °C is the continuous current it carries in a typical 40 °C panel ambient. At 50 °C it derates to 14 A; at 70 °C it holds 13 A. That derating curve matters if the breaker sits near transformers or drives that push the enclosure above 40 °C. The 65 kA at 240 V means it can safely interrupt a bolted fault up to that level — typical for 240 V distribution in North American commercial and light industrial panels. At 480 V the interrupting rating drops to 25 kA, still adequate for most motor-control-center feeds.
Panel fit and footprint
The 3VA4195-4ED34-0AA0 measures 76.2 mm wide, 75.1 mm deep, and 129.4 mm tall. That width is the standard 3-pole MCCB footprint for this SENTRON frame — it mounts directly onto a DIN rail or panel baseplate without adapters. The IP40 front protection means it's suited for enclosed panel mounting where no washdown or direct spray is present. No undervoltage release, no communication module, no motor drive option — it's a straight thermal-magnetic breaker with no auxiliary electronics to fail.
