Its breaking capacity class N means it handles 25 kA at 415 V — enough for most distribution boards downstream of a transformer, but not for high-fault main incomers where class S or H would be specified. Rated at In=32 A with a TM220 (thermal-magnetic) trip unit, the overload protection Ir adjusts from 22 A to 32 A, and the short-circuit protection Ii is fixed at 10 × In (320 A). That 10× multiplier is standard for motor-starting loads — it rides through inrush without nuisance trips on pumps or small conveyors. The 100% N-conductor protection means the neutral pole is fully rated, not reduced, so it handles unbalanced loads without derating. The nut keeper kit and DC Power OEM marking suggest this variant was configured for a specific Chinese OEM assembly — the hardware is standard 3VA1, but the accessory kit and factory-set parameters lock the BOM.
Because the DC Power OEM suffix (ZD00) is a factory-customized variant, lead times may run longer than the base part 3VA1132-3GE42-0AA0.
Panel integration
Mounts on standard DIN rail in a distribution or motor control center enclosure. The 4-pole footprint takes up four modular-width spaces — plan your gland plate and busbar routing accordingly. Terminal torque values and wire strip lengths follow the 3VA1 installation manual; no special tools beyond a flat-blade screwdriver.
