Overview
The Corcom 3VR1 is a compact, single-phase EMI filter designed to suppress electrical noise and interference in industrial and commercial power systems. Part of Corcom’s R Series product line, this filter is rated for 3A at 120/250V, 50-60Hz operation. The 3VR1 combines L-C filtering topology with two filter stages to provide reliable EMI/RFI suppression while maintaining compact panel-mount dimensions. This used, tested unit is suitable for retrofit applications requiring drop-in EMI filtering protection.
Key Features
- 2-stage EMI/RFI filtering — dual-stage LC network architecture for noise suppression
- 3A current rating — suitable for single-phase industrial loads
- 250VAC voltage rating — compatible with 120/250V dual-voltage systems
- Quick-connect terminals — 0.25″ spade lugs for standard panel mounting
- UL/CSA approved — designed and tested per major safety agency standards
- Compact panel-mount form factor — space-efficient integration into electrical enclosures
