It is a dedicated 12-pulse ammeter — meaning it reads the DC bus current on a 12-pulse rectifier configuration, not the standard 6-pulse line current. If your drive is a 12-pulse unit for harmonic mitigation, this is the correct metering accessory. This accessory is specific to Altivar floor-standing enclosures with separate air flows or the compact version — not the standard IP20 wall-mount drives. If you are retrofitting or repairing a 12-pulse Altivar 61 Plus or 71 Plus cabinet, the VW3AE0421 mounts into the door or subpanel and connects to the DC bus sensing terminals. No other drive family shares this form factor or pinout.","metaTitle":"VW3AE0421 Altivar 61/71 Plus Ammeter, Obsolete – Sourced to","metaDescription":"VW3AE0421 ammeter for 12-pulse Altivar floor-standing enclosures.
