What this MCCB is and what the ratings mean
The SENTRON 3VA1180-5ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 80 A continuous current, with a TM210 thermal-magnetic overcurrent release. That 80 A holds steady from 40 °C up to 50 °C ambient — no derating needed in a warm panel — then drops to 78 A at 55 °C and 74 A at 70 °C. The breaking capacity tells you where it can safely interrupt a fault: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V or 690 V. For a line-protection MCCB, those numbers mean it handles high-fault-current scenarios like transformer secondaries or large motor branch circuits without cascading upstream.
Panel fit and integration
The breaker measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a standard MCCB footprint that drops into most SENTRON distribution panels or standalone enclosures. Four poles mean it switches all phases plus neutral in a single unit, saving rail space over a 3-pole breaker plus separate neutral block. Power loss is 19.2 W maximum, so factor that into enclosure thermal calculations if you're packing multiple breakers in a sealed cabinet.
