Switchgear is an important component of power systems, and ensuring the safety of switchgear is essential for the well-being of your employees and the efficiency of your operations. One effective way to improve switchgear safety is through the use of trapped key interlocking systems.

What is Trapped Key Interlocking and How Does it Work in Switchgear?



Trapped key interlocking is a type of safety system that uses a series of locks and keys to control access to hazardous areas of machinery. In the context of switchgear, trapped key interlocking can be used to ensure that power isolation procedures are followed before access to the switchgear is granted.






For example, a trapped key interlocking system may require an operator to insert a key into a lock to unlock a panel before they can access the switchgear. This key is then “trapped” in the lock, preventing the switchgear from being energized until the key is released.

The Benefits of Using Trapped Key Interlocking in Switchgear

Trapped key interlocking systems provide a number of benefits for switchgear safety, including:


  • Helping to ensure compliance with safety regulations and standards
  • Reducing the risk of incidents and injuries
  • Improving power isolation procedures
  • Increasing the overall safety of your switchgear and power systems
