Product Details | OVERVOLTAGE ABSORBER
5920-01-187-5939 An item specifically designed to absorb and consume surges of voltage such as that resulting across contacts when breaking a circuit having an inductive load or a burst of static across a telephone receiver. It is connected in parallel with the item it is protecting. It may be made up of metallic rectifier cells or semiconductor devices connected back-to-back which may or may not be shunted by a capacitor. It may also be a single rectifier cell or semiconductor device shunted by a capacitor. Excludes metallic rectifiers which are rated for rectifying capabilities and all single unit semiconductor devices not shunted by a capacitor. For items perfoming this function by use of voltage sensitive resistors, see RESISTOR, VOLTAGE SENSITIVE. See also CUTOUT DISK, PROTECTIVE.

What Our Customers Say
Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
