Surge and Filter Protection — Bulletin 4983

Rockwell Automation is pleased to introduce the Bulletin 4983 Surge & Filter Protection product line to meet the needs of industrial surge and filter protection requirements. Bulletin 4983 Surge & Filter Protection products are crucial for protection against internally generated transient and high frequency noise.

The Importance of Protection

Any load switching that creates a spark has the potential to produce damaging transients within your system that can destroy equipment if not addressed. Motor drives, contactors, and capacitor bank switching are just a few examples of transient sources.



Noise is unwanted disturbance in your power line. Examples of noise sources are variable speed drives and computerized industrial loads. Premature aging and system interference is common to equipment without protection.



Transient and high frequency noise often go undetected until it is too late. It is not until equipment is damaged that the importance of surge and filter protection is recognized. Planning your protection is less problematic and can be less costly than reacting to a failure later. Be proactive and recognize the importance of implementing surge and filter protection as part of your industrial environment.
