The Siemens SENTRON 3VA1180-6EF32-0HC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current Iu of 80 A at 40 °C and an insulation voltage Ui of 800 V. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. The 17 kA at 690 V still covers most industrial 690 V distribution. Thermal derating is minimal up to 50 °C (still 80 A), then steps down to 76.8 A at 55 °C and 72 A at 70 °C. For a panel running warm — say 55 °C ambient — you lose about 3.2 A of headroom; plan the load accordingly.
Two auxiliary switches (HQ type) are built in. No undervoltage release or communication module is fitted — this is a basic trip unit for simple remote shutdown via the shunt coil.
Deployment context
The 3VA series is the SENTRON MCCB family, positioned as a compact, high-performance line for commercial and industrial power distribution. This variant is a line-protection device — no phase-failure detection, no ground-fault monitoring — so it's a pure overcurrent protector for feeders or branch circuits.
