Overview
The MA20-4 is a single-phase EMI/RFI power line filter manufactured by Tri-Mag, LLC. Designed for industrial and business applications, this component provides electromagnetic interference suppression for AC power circuits. It supports input voltages of 115V or 250VAC at frequencies of 50Hz or 60Hz. The unit is rated for a continuous current of 20A. Key internal components include X2 class capacitors with capacitance values of 1.0µF and 1.5µF in shunt configuration. The device is RoHS compliant and typically supplied in bulk packaging.
Feature Summary
- Provides single-phase EMI/RFI noise suppression for AC power lines
- Supports dual voltage ratings of 115VAC and 250VAC
- Utilizes X2 class capacitors for safety-rated filtering
- RoHS compliant construction for environmental standards
Applications
- Industrial machinery power inputs
- Business equipment AC power conditioning
- Single-phase AC power distribution systems
Procurement Notes
Verify the specific datasheet version for the MA20-4 to confirm mechanical dimensions and terminal types. Ensure the application environment matches the 20A current rating and 115/250VAC voltage specifications. Confirm RoHS compliance requirements if applicable to your project. Check for any specific mounting hardware requirements associated with the bulk package format.
Selection Notes
Select the MA20-4 when a single-phase EMI filter is required for 20A loads operating at standard 50/60Hz frequencies. This model is suitable for applications needing suppression of both conducted emissions and susceptibility on AC lines. Consider the physical size constraints and the need for X2 capacitor safety ratings. Evaluate if the fixed 20A rating aligns with the maximum load current of the target system.
Part Context
Tri-Mag, LLC specializes in manufacturing power conversion components, including AC-DC supplies and EMI filters. The MA20-4 belongs to their line of power line filters designed for reliability in commercial and industrial settings. As a subsidiary of Curtis Industries, Tri-Mag leverages established engineering practices for these passive filtering solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for cross-reference options based on identical electrical parameters such as 20A rating and single-phase configuration.
