Enclosed switches. Load switches / disconnectors according to IEC 60947-3 also for use as safety switches where required. According to current regulations, safety switches must be connected in the main circuit in order to separate the installation part during mechanical or electrical work and to prevent accidental connection of such load during work in progress. When a safety switch is to be used only to separate the load, it is necessary to have both an electrical switch for start and stop in a load''''s electrical circuit and a separate electrical switch as a safety switch. Load switches / disconnectors according to IEC 60947-3 can be used either as a safety switch or as a separate electrical switch.
