Industrial 803456-21T Power Module

Reliance Electric's 803456-21T DCS Field Supply Module delivers 460 VAC three‑phase field power to Reliance Automax/Automate drives. It sits in a three‑sided metal carrier with a removable cover secured by four screws, exposing a terminal strip and external connectors for system integration. Inside, the board is designated 0‑57300 and is populated with eight transformers, stab‑on connectors, terminal pin connectors, and two right‑angled cable connectors; fuses and a transformer (TR‑12731) sit beneath the board. The 803456‑21T is a three‑phase, 460 VAC field supply used in Reliance drives and their auxiliaries, and components from this lineage were sometimes sold under the Baldor‑Reliance or ABB branding. This module is part of the DCS field supply for Reliance Electric systems and is designed to support Automax/Automate configurations requiring a 3‑phase 460 V source.
