TCI KRF0250VCB TCI, RFI, 3-Ph, 250Amp

The KRF filter reduces high frequency distortion and noise in the 150 kHz to 30 MHz range, protecting sensitive equipment from interference.

System voltage can be 480 VAC (applied to 240 VAC - 520 VAC) or 690 VAC (applied to 600 VAC - 760 VAC).

For 480V systems, amp ratings are 8 - 2500. For 690V systems, amp ratings are 25 - 2500.

The filter can handle 150% rated current for 3 minutes every 60 minutes, or 250% for 3 seconds every 60 minutes.

It uses a combination of high frequency inductors and capacitors to reduce noise in the 150 kHz to 30 MHz range.

KRF filters can operate in ambient temperatures from -25° to 100° C and at altitudes up to 1,000 m without derating.

KRF filters are useful for motor drives, elevators, commercial buildings, wind farms, photovoltaics, UPS, and power supplies.

KRF filters have ENEC and UL Recognized agency approvals.

Disturbances include computer system failures, remote I/O glitches, encoder feedback errors, and nuisance PLC faults.

Termination options include Termination Block (TB) and Copper Bus (CB).
