Transient Voltage Suppressors from CCI

Pass UL 497B Listed Requirements

Tempe, AZ--Circuit Components, Inc. (CCI), has been notified that its SAB and SPU series of surge suppressors have recently passed the UL 497B listed requirements for data communications and fire alarm circuits.

Underwriters Laboratories, North Brook, IL, conducted the testing. The devices tested were Series SAB and SPU data protectors, consisting of daughter modules plugged into base modules. These hybrid-type surge suppressors provide electronic filtering and add transient suppression for the protection of I/O modules from all major manufacturers.

The SAB/SPU Series protects the AC, DC, contact output, current output and signal input lines of I/O modules. They are used in data transmission applications, telecommunications equipment, 4-20mA loops, and general purpose applications.

The SPU surge protector is a hard-wired version that uses miniature field screw terminals for the connection between the input and the I/O equipment connection. The SAB differs from the SPU in that it uses a latch connector for interconnections with Allen Bradley I/O modules. This connector is identical to those used in the 1492-IFM Series of interface modules.

Antonio Valles, CCI Director of Marketing, notes that surge protectors carrying this low UL voltage breakdown rating (clamping voltage) will protect electronic equipment against extremely fast transients of up to 100 Volts per microsecond.

CCI offers a broad line of electrical suppression and filtering devices, with a choice of over 200 models. The company provides the most comprehensive line of transient suppression and filtering products in the industry.
