Siemens 3VA4180 6ED34 0AA0 3VA4 Circuit Breaker

Siemens 3VA4180-6ED34-0AA0 is a three-pole molded‑case circuit breaker in the 3VA4 UL frame family, designed for distribution panels and motor circuits in industrial and commercial settings. It provides a nominal current rating of 80 A (In) and uses the TM210 trip unit with fixed thermal‑magnetic protection (FTFM), delivering overload protection Ir=80 A and short‑circuit protection Ii=10 x In. Rated for up to 480 V, this version offers a high interrupting capacity of 65 kA at 480 V (H‑interrupting class), ensuring fast disconnection under fault conditions; note that other 3VA4 variants (for example 3VA4180-4ED34-0AA0) are listed with 25 kA at 480 V (S‑interrupting class). The unit is a three‑pole device and uses standard terminal connections for field wiring, matching the 125‑frame footprint common to the 3VA4 lineup. In service, it protects feeders and equipment in panelboards and switchgear by combining precise overload protection with robust short‑circuit interrupting performance while occupying a compact phase‑balanced package that fits in typical industrial electrical distribution installations.
