What the ratings mean for fit
The 3VA2010-6JP36-0AA0 is a Siemens SENTRON molded case circuit breaker rated for 100 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed as the panel warms up near a furnace or drive cabinet. The ETU550 electronic trip unit gives adjustable overload and short-circuit protection curves, not just a fixed thermal-magnetic response, which matters when coordinating with downstream feeders on a glass-melting line that holds the thermal profile. Breaking capacity reaches 242 kA at 240 V and 187 kA at 415 V, so it clears high-fault conditions without cascading upstream — sized for a main breaker position in a 480 V panel feeding multiple motor loads.
Panel footprint and integration
Three-pole construction, 105 mm wide, 181 mm tall, 86 mm deep — fits the standard MCCB cutout in a SENTRON distribution panel or a generic enclosure backplate. IP40 on the front means the operator face is protected against tools and small wires; the interior is not sealed, so mount it in a clean, dry enclosure. At 13.5 W maximum power loss, the heat it dumps into the cabinet is modest — no forced cooling needed for a single unit, but group several breakers and check the enclosure's thermal budget.
