Do You Know Your Motor Drive?

Industrial Drive
above: ABB Industrial Drive -- ACS800. They are complete AC variable speed drives, which can be installed without any additional cabinet or enclosure and used in process industries such as pulp and paper, metals, mining, cement, power, chemical, and oil and gas. [ABB ACS800 industrial AC inverter drives with direct torque control (DTC) as standard are available both as complete AC drives and as modules to meet the requirements of the users, OEMs and system integrators. The ACS800 range of ac inverters are highly flexible and can be configured to meet the precise needs of industrial applications, and hence order-based configuration is an integral part of the offering.]

Motor Starter: This Siemens isolator module with its switch disconnector function serves to safely isolate the 400 V operating voltage when repair work is being carried out in the plant. It features an integrated group-fusing function, i.e. additional group short-circuit protection for all series-connected motor starters. Depending on their power distribution concept, all stations can be optionally fitted with an isolator module.
