TeSys F mechanical block for up to 2 horizontal contactors LA9FJ970

Mechanical lock for TeSys F contactors

This element protects TeSys F series contactors against accidental activation or unauthorized modification of settings. The LA9FJ970 mechanical lock is designed for mounting on two horizontally arranged contactors, providing additional safety and reliability of the electrical installation. This is particularly important in industrial applications where the risk of incorrect operation can lead to downtime or equipment damage.

Application and compatibility

The LA9FJ970 lock is dedicated to TeSys F contactors, guaranteeing a perfect fit and easy installation. It provides physical immobilization of the contactor's working elements, preventing accidental switching. This is crucial in situations where maintaining a stable circuit state is required, e.g. during maintenance or repair. This allows installers and service technicians to safely work on energized equipment, minimizing the risk of electric shock.

Construction and mounting

The lock is made of durable materials, resistant to mechanical damage and external factors. Installation is simple and intuitive – the lock is placed on the contactors and secured with standard screws or clips (detailed mounting instructions can be found in the technical documentation of TeSys F contactors). The lock design provides quick access to the contactors if unlocking by authorized personnel is necessary. This allows for efficient servicing without having to disassemble the entire installation.
