Protector for telecom applications

2 November 2005 Circuit & System Protection

With the new Protector 950, Wickmann has expanded its range of overcurrent protection components for telecommunication applications. Designed to protect telecom lines against overcurrents, the lead-free protector is packaged in the proven, small-size TE5 housing and offers superior pulse load capabilities. Featuring 50 A/ 250 V a.c. breaking capacity, a rated current of 1,6 A and a long time-lag characteristic, the compact protection device is well-suited for a variety of telecom systems and networking equipment.

The special melting element of the Protector 950 eliminates electrical specification variations caused by high pulse load conditions and provides a major advantage over conventional protectors. High magnetic field strength under pulse conditions can cause mechanical displacement of the melting element in conventional protectors. This leads to an unwanted change of the current rating, impairing reliable protection. The Protector 950 meets demanding pulse handling requirements according to FCC 47 Part 68, ITU TK.20 and Telcordia GR 1089. The very low inner resistance ensures a minimum affect on the signals.

Wickmann manufactures the RoHS-compliant Protector 950 in direct solderable and plug-in versions with shocksafe casing. It was developed to fulfil the planned expansion of IEC 60950 standards and is specified for operating temperatures from -40 to +85°C. It measures 8,5 x 4,0 x 8,5 mm.
