Trapped Key Interlocking Systems for Electrical Distribution 

Trapped key interlocks are mechanical or electro-mechanical devices used to ensure the safe operation of plant and equipment.

Teksal Safety is a long-time distributor of Fortress Interlocks, offering years of experience with trapped key interlock applications and distribution interlocking project management. Typical applications of trapped key interlocks include:

  • Safe Isolation & Access Control – ensures isolations are complete before  personnel can access machinery or equipment.

  • Switchgear interlocking and HV switching – helps minimise switching and isolation risks in complicated distribution systems.
