What it is and where it fits
The 3VA1180-5ED32-0AA0: This is a Siemens SENTRON 3VA1 molded case circuit breaker, 3-pole, rated 80 A continuous at 40 °C with a TM210 thermal-magnetic trip unit. It's built for line protection — think main feeder or large subfeed in a distribution panel, not motor-starting duty. The 187 kA interrupting rating at 240 V gives you serious fault-clearing headroom on a low-voltage service entrance or a high-capacity busway tap.
Ratings that matter for the install
The TM210 release is a fixed thermal-magnetic — no interchangeable trip units, so what you order is what you get. At 40 °C it holds 80 A; derate to 74 A at 70 °C if the panel runs hot. Interrupting capacity drops as voltage climbs: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 or 690 V. That 17 kA at 690 V is still enough for most industrial 600 V class systems, but verify coordination if you're on a high-fault 690 V bus. Insulation voltage rated 800 V, so the breaker itself is fine on 690 V systems. IP40 on the front — splash protection on the face, but the terminals are open; mount it in a dead-front enclosure or a panel with a door.
Physical fit and panel integration
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 70 mm depth is shallow enough for most 200 mm deep enclosures with wiring gutters. Three-pole, so it occupies a single 76.2 mm module on the DIN rail or mounting plate — standard 3-pole MCCB footprint. No undervoltage release, no shunt trip, no communication module on this variant; it's a straight thermal-magnetic breaker with no auxiliaries.
