Description
Allen-Bradley 1497-E-M4-3-N Multi-channel Transformer
Product Dimensions:
The Allen-Bradley 1497-E-M4-3-N is a high-quality Industrial Control Transformer from the 1497 series. These transformers are specifically designed to reduce supply voltages to lower voltages for the operation of electromagnetic devices such as contactors, solenoids, relays, and timers.
Product Detailed Description
The 1497-E-M4-3-N is a multi-tap transformer that offers high-performance voltage regulation, particularly during the high “inrush” current periods typical of industrial control circuits. The “N” in the part number indicates it is a Global Control Transformer, built to meet international standards (UL, CSA, and CE). It features integrated finger-safe terminals to improve safety during installation and maintenance.

Product Advantages
- Superior Voltage Regulation: Designed to exceed NEMA ICS-2 standards for inrush regulation, ensuring that control devices close reliably even under heavy loads.
- Global Compatibility: The multi-tap primary allows one unit to be used in various voltage environments (208V, 240V, or 480V), reducing inventory costs for OEMs.
- Enhanced Safety: The terminal blocks are designed to be “finger-safe,” preventing accidental contact with live electrical parts according to IP2X standards.
- Durable Construction: Features vacuum-impregnated coils to provide high dielectric strength and resistance to moisture and industrial contaminants.
- Compact Footprint: High-efficiency core materials allow for a smaller physical size relative to its VA rating, saving space in control panels.
Important Considerations (Precautions)
- VA Sizing: Before installation, ensure the Total Inrush VA of your control circuit does not exceed the transformer’s maximum rating. Undersizing can lead to excessive voltage drops and “chattering” contacts.
- Fusing: This transformer does not include primary or secondary fuses by default. It is highly recommended to install a 1497-FUSE kit (optional accessory) to protect against short circuits and overloads.
- Environment: Ensure adequate ventilation within the enclosure. The transformer generates heat during operation; blocking airflow can lead to premature failure or tripping of thermal protection.
- Torque Requirements: Use the manufacturer-specified torque for terminal screws to ensure a secure electrical connection and prevent arcing.
Product Applications
The 1497-E-M4-3-N is widely used in industrial automation and power distribution:
- Motor Control Centers (MCCs): Stepping down 480V line power to 120V to power the coils of NEMA or IEC motor starters.
- Machine Tool Control: Providing stable control power for CNC machines, lathes, and milling equipment.
- HVAC Control Panels: Operating heavy-duty contactors and dampers in commercial air conditioning systems.
- Process Automation: Supplying power to 120V AC PLC power supplies, pilot lights, and industrial sirens.
