Delta 50TYSW11 440V 3-Phase 50A EMI Line Filter (Used Condition)

Description

The Delta 50TYSW11 is a 3-phase EMI (electromagnetic interference) power line filter, manufactured by Delta Electronics for use on higher-power industrial equipment. Housed in a rugged, foil-wrapped metal enclosure for shielding and heat dissipation, it's designed to suppress conducted electrical noise on 3-phase AC power lines, helping equipment meet EMC compliance standards while protecting against interference from the mains supply.

As printed on the label, this filter is rated for 440V, 3-phase (3φ), 50A operation at 50/60Hz, making it suited for demanding industrial power applications such as motor drives, CNC machinery, industrial power supplies, and other 3-phase powered equipment. The internal filter network is built from an inductor array (L: 4x0.3mH) and capacitor network (2.2µF X2SH capacitors, plus 2200pF Y1 capacitors), with 200KΩ bleeder resistors for safe discharge.

The unit comes with pre-wired input/output leads — including brown, black, white, and green/yellow (ground) wires along with a connector harness — for direct integration into existing power wiring. It carries UL/cUL and CSA (S) safety certifications, and is clearly marked with LINE and LOAD orientation for correct installation.
