Original Press Release:
New Surge3 Suppressor Offers a Choice of Two Protection Technologies In a Plug and Play Package
ST. LOUIS-Advances in digital technology make industrial control equipment increasingly vulnerable to transient voltage. Cooper Bussmann®, known for its expertise in circuit protection, now offers the Surge3, a solution for overvoltage protection of industrial electronics. The housing for the Surge3, based on the previously released CUBEFuse(TM) platform, allows for simple yet effective installation to protect PLC, HMI/VCP (video control panel), PID controllers, industrial computers, variable speed drive, and vision systems.
This unique surge suppressor offers the customer the choice of two technologies-MOV and Diode-both interchangeable with a plug-in suppressor and common base mount. MOV protection, most recognized in the industry, is an economical way to suppress transients. Diode protection is state-of-the-art technology for protection of critical equipment. Bussmann uses computer matched, high power cell diodes in an advanced diode array. This diode design offers low clamping with high surge current ratings.
The Surge3 system is color coded for proper installation. All suppressors and bases are labeled with specific voltage colors. Matching the color helps achieve the proper selection of appropriate initial and replacement components. The Surge3 is UL recognized.

WHY SHOULD I USE A SURGE SUPPRESSOR?
"I didn't hear of this problem until recently."
Advances in technology make today's digital equipment increasingly vulnerable to transients. Power quality problems will continue to grow and affect more installations.
"I already use Isolation Transformers."
The Isolation Transformer is used to provide a solid ground, which helps eliminate noise. Typical response time with respect to surges is measured in milliseconds. Surge duration is typically measured in nanoseconds; therefore, a surge can pass right through an Isolation Transformer.
"I already use a UPS."
The UPS (uninterruptible power supply) is used to provide backup power in case of an outage or brownout. The UPS uses a simple filter, which can eliminate some transients. Protection is
limited to the frequency band of the filter, so surges outside that band pass through the UPS. Some UPS systems offer MOV surge protection, which have a high surge let-through and degrade over time. Since the UPS is an electronic device, it is recommended that a suppressor be used to protect a UPS.
"I'm solidly grounding all my panels."
Grounding is the primary cause of power quality problems. Proper grounding solves noise problems. Once proper grounding is achieved, surge suppression is the next largest problem to
tackle. Proper grounding does not protect against surges.
"I have a dedicated line to protect power to my critical application." Dedicated lines protect against internally generated surges, but actually offer a lower impedance
path for externally generated surges such as lightning or utility grid switching.
"I haven't had any downtime problems so I must not need surge protection." Surges are common to all electrical systems, and usually cause slow degradation. The question is not if you will have surge problems, but when. Most people install surge protection after they've experienced a problem. The best protection is prevention.
