This equipment prevents the unintentional activation of switching devices, e.g. during maintenance work. The DEASS on/off interlock prevents miniature circuit-breakers from series DLS 6 from being switched on or off. On the one hand, the DEASS can be used to implement protective measure "secure against restart" during maintenance and repair work, and on the other, it protects sensitive circuits from being switched off inadvertently, such as in IT systems, UPS installations and alarm systems. The interlock can be sealed or secure using a conventional padlock (shackle diameter up to 6 mm). The protective function of the miniature circuit-breaker is not affected by the use of the DEASS due to its trip-free mechanism.

quick and universal use, sealable, lockable with a conventional padlock

Mounting directly on the toggle of the switching devices

For general protection from switching on or off power supplies to residential and purpose-built buildings as well as industrial facilities.
