80 A fixed thermal-magnetic, 25 kA interrupting capacity
The Siemens SENTRON 3VA1080-3ED46-0AF0 is a 4-pole molded case circuit breaker (MCCB) in the 3VA1 frame, rated 80 A continuous with a fixed TM210 thermal-magnetic release. Overload protection Ir is fixed at 80 A; short-circuit pickup Ii is fixed at 10 × In (800 A). The interrupting capacity is 25 kA at 415 V AC (breaking capacity class N per IEC 60947-2), which covers most commercial and light industrial panelboard fault levels without cascading upstream.
Line protection version, 4-pole with unprotected neutral
This is the line protection version — no voltage trip, no undervoltage release, no ground-fault monitoring. The fourth pole switches the neutral conductor but provides no overload or short-circuit protection on that pole (N conductor unprotected). Front-terminal lug connections accept standard panel wiring. The auxiliary contact configuration is one auxiliary switch plus one trip alarm switch, both HQ type; the integrated switch order code is 3VA9988-0AB12.
Environmental and mounting limits
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Front-face protection is IP40 — suitable for enclosed panel mounting where no water ingress is expected. The 3VA1 frame is designed for DIN-rail or screw-mount integration in standard distribution boards.
