The document provides an overview of contactors, which are electromagnetic switches designed to manage high-load devices, with a history of LG Industrial Systems and its range of products. It details the specifications, frame sizes, and capabilities of various contactor models, including their applications in switching electric motors and other high current devices. Additionally, it includes information about overload relays and ancillary products, as well as a quiz to assess knowledge on the material presented.
Dalroad Norslo - Electric Equipment - Contactor training level 1 - LS Industrial Systems (former LG)
- 2. What is a Contactor? A contactor is a form of switch contacts that are operated by an electro magnetic coil.......the same principal as a relay. The main different being is that a contactor is designed to switch much larger loads, anything up to 800amps! So who manufactures our contactors?
- 3. A brief History Korean based LG Industrial Systems was originally formed in 1974. As a company LG Group offer a wide range of products and services from domestic appliances to Petrol Chemical and Industrial systems. LG as a brand has grown into one of the worlds most recognised brands, know for quality and leading edge technology. In 2005 LG Group was split into 3 divisions operating independently. LG (Electronics), GS (Petrol Chemical) and LS (Industrial Systems). In 2008 LS Industrial Systems choose Dalroad Norslo Ltd as its distribution partner in the UK. Supplying and supporting the LS range of low voltage products.
- 4. Where are Contactors Used? They can be used to switch high current devices such as electric motors, industrial heaters, fans, water pumps, industrial lighting and control panels.
