Allen-Bradley 1497-F-BASX-3-N Control Circuit Transformer

Configured for control voltage transformation in industrial power distribution networks, the Allen-Bradley 1497-F-BASX-3-N (1497-F-BASX-3-N Control Circuit Transformer) provides direct electrical execution by converting 240/480 VAC or 220/440 VAC supply voltages to 110 VAC or 120 VAC control circuit levels. The transformer incorporates provisions for two primary fuse blocks and one secondary fuse block for circuit protection.

Suffix Breakdown & Model Matrix

The catalog number 1497-F-BASX-3-N is specified as a fixed transformer assembly. No manufacturer-defined suffix matrix or configurable ordering breakdown is provided in the available documentation.

Hardware Specifications

Backplane Power Distribution and Control Voltage Architecture

The 1497-F-BASX-3-N functions as a power conversion component supplying reduced control voltages to PLC cabinets, relay logic circuits, contactor coils, and associated control devices. The transformer operates independently of controller backplane communications and network traffic.

In control panel architectures, the 350 VA capacity allows distribution of secondary control power while maintaining isolation between supply and control circuits. The integrated fuse block arrangement permits independent protection of primary and secondary transformer circuits according to installation requirements.

Field Installation Guidelines

• Verify primary voltage tap selection before energizing the transformer.

• Install primary and secondary overcurrent protection devices according to applicable electrical codes and equipment documentation.

• De-energize all supply circuits before wiring or maintenance activities.

• Maintain separation between control wiring and higher-current power conductors within the enclosure.

• Ensure adequate enclosure space for transformer heat dissipation during continuous operation.

• Verify all terminal connections are mechanically secure before commissioning.

• Connect protective grounding conductors in accordance with local electrical standards.

• Inspect fuse holders periodically and replace protective devices only with correctly rated components.
