What this MCCB is and what the ratings mean for your panel
The Siemens 3VA1080-3ED32-0HA0 is a 3-pole SENTRON molded case circuit breaker rated for 80 A continuous current at 40 °C through 50 °C, with a TM210 thermal-magnetic overcurrent release. The interrupting capacity tells you where it can safely clear a fault: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — so at 415 V it handles the full 50 kA typical of a large distribution transformer secondary without needing a current-limiting upstream device. The TM210 release means the thermal element tracks the cable temperature, and the magnetic pickup is fixed at 10× Iu (800 A), which is standard for line protection of cables and busbars, not motor starting. No undervoltage release, no auxiliary contacts, no communication module — this is a bare breaker with a shunt trip (STL) for remote opening. The IP40 front rating means it's protected against tools and wires >1 mm, fine for a clean indoor panel; don't install it in a washdown zone.
Panel fit and footprint
The 3VA1080-3ED32-0HA0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters without re-drilling. The shunt trip coil (STL) is factory-installed; verify the control voltage matches your trip circuit before wiring. No auxiliary contacts or undervoltage release means you'll need to add those externally if the BOM calls for status feedback or undervoltage lockout.
