STC Module

Surge arrester for earthed socket outlets

For protecting electronic devices against surges. For use with standard earthed socket outlets. For installation in conformity with the lightning protection zone concept at the boundaries from 1 – 2 and higher.
  • Two-pole surge arrester with monitoring device and disconnector
  • Enhanced safety due to fault-proof Y protective circuit
  • Acoustic fault indication
  • For installation in standard earthed socket outlets
  • Independent of the socket outlet design
  • Plastic snap-on retaining ring for easy installation in already mounted socket outlets

Version

STC 230: Snap-on module for standard earthed socket outlets

Details

The well received two-pole STC surge arrester can be fitted inconspicuously on the rear side of many standard earthed socket outlets. The STC surge protection module thus adapts to every type of socket outlet. The plastic snap-on retaining ring allows easy installation even in already mounted earthed socket outlets. In addition to a thermal disconnector, the protective device features an acoustic fault indication. As the surge protection module is installed in parallel to the socket outlet, the power supply of the connected loads remains uninterrupted, even if the surge arrester is overloaded.
