STC Module
• 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

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.

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

The popular 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 protec-
tive 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 consumers remains uninterrupted, even if the surge arrester is
overloaded.
