What this 4-pole MCCB carries
The Siemens 3VA1080-3ED46-0AA0 is a SENTRON 4-pole molded case circuit breaker rated 80 A continuous at 40 °C, with a TM210 thermal-magnetic release. That 80 A holds flat through 50 °C — no derate needed in a warm panel — then drops to 78 A at 55 °C and 74 A at 70 °C. The interrupting ratings climb to 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, so it handles high-fault service-entrance or distribution positions without cascading upstream.
The 3VA1080-3ED46-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole footprint that fits standard MCCB panel cutouts.
What the TM210 release means for coordination
The TM210 is a thermal-magnetic release — thermal for overload (adjustable, typically 0.7–1.0× In) and fixed magnetic for short-circuit. No electronic adjustment or communication module here, so selectivity studies rely on the published time-current curve.
