Tip: Precautions for isolator switch operation

1. During the overhaul of electrical equipment, provide an electrical interval and a clearly visible disconnection point to ensure the personal safety of maintenance personnel.
2. Isolating switch cannot be operated with load: it cannot be operated with rated load or large load, load current and short-circuit current cannot be divided or combined, but the circuit with small load and no-load circuit can be operated with arc extinguishing chamber.
3. In general power transmission operation: first close the isolating switch, then close the circuit breaker or load switch; when the isolating switch is powered off: disconnect the circuit breaker or load switch first, and then disconnect the isolating switch.
4. The selection is the same as other electrical equipment, and its rated voltage, rated current, dynamic stable current, thermal stable current, etc. must meet the needs of the use occasion.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
