The 3VA1132-6EF32-0AA0-ZD00: This is a 3-pole IEC frame 160 circuit breaker with breaking capacity class H — Icu=70kA at 415V AC. The thermal-magnetic trip unit is TM240 with ATAM (adjustable thermal and magnetic): overload protection Ir is adjustable from 22A to 32A, and short-circuit protection Ii is set at 5 to 10 times In (160A to 320A at the 32A tap). That adjustability lets you fine-tune protection to the downstream load without swapping the breaker.
Deployment context
The nut keeper kit included with this variant is specified for DC Power OEM builds in China — a detail that matters if your BOM is destined for that region and the assembly line expects captive hardware for the busbar connections. Mounts in a standard IEC distribution panel or motor control center; the 3VA1 platform shares the same DIN-rail or screw-mount footprint as the broader 3VA family, so panel cutouts and busbar layouts transfer across ratings.
