The three interlocks have a similar design to ensure optimum consistency, but each has been developed for locking its own group of circuit breakers.

The S3821 is for all miniature circuit breakers (120/240V). The compact size ensures that also the neighbouring circuit breakers can be locked. This interlock is simply fixed by means of a belly screw, so no screwdriver is needed.

The S3822 is for closed circuit breakers (480/600 V). This interlock fits circuit breakers with moulded case, and is compatible with a wide variety of shapes and sizes of circuit breakers. It is easily tightened by a large knurled screw and no tools are required for installation.

The S3823 is a lock for circuit breakers with large handles (480/600 V). This interlock is compatible with an extra wide variety of shapes and sizes of circuit breakers. And no additional tools are required for installation.
