FAQs
Mounting the Eaton C0250E2AFB in a standard control panel requires providing adequate clearance for heat dissipation, securing the epoxy-encapsulated transformer to a stable mounting surface, and wiring to the molded-in terminals. With no taps, ensure the primary connections match the chosen voltage pair (220/440, 230/460, or 240/480 V) and keep conductor sizes within the transformer’s terminal ratings. The optional two-pole primary fuse block should be used only where protection is required by the application.
This transformer supports primary voltage configurations of 220/440 V, 230/460 V, and 240/480 V and provides a secondary output of 120/115/110 V. There are no taps. The wide primary range enables deployment across regional power grids, while the fixed secondary supports standard low-voltage control circuits in automation equipment.
The C0250E2AFB is UL Listed, cUL Certified, and CSA Certified, with RoHS compliance. These certifications verify product safety, performance, and environmental standards, facilitating regulatory approval, reducing supplier risk, and ensuring compatibility with globally sourced components in OEM panels and end-use equipment.
The 250 VA rating provides ample low-voltage power for relays, contactors, and PLC I/O modules in typical panel applications. This rating supports stable control power under peak coil inrush conditions while allowing appropriate protection devices, such as the factory-mounted two-pole primary fuse block, to guard against faults and minimize downtime.
Maintenance benefits come from robust epoxy encapsulation, copper windings, molded-in terminals, and a durable enclosure that reduces loose connections and heat-related failures. ROI is driven by longer transformer life, fewer field service calls, faster panel assembly, and regulatory compliance reducing procurement risk for multi-region deployments.
