| Video Discription | A lot of people get really confused by contactors and relays and tend to treat them like some kind of mystical magic device without understanding what exactly they do. They have some similarities but still have very distinct differences. 00:00 Intro 00:27 How Are They Similar? 01:33 How Do They Differ? 04:22 Outro 👾🤖PRACTICE EXAMS🤖👾 https://www.electricianu.com/practice-exams 😎👕MERCH👕😎 https://www.electricianu.com/merchandise 📲👥SOCIALS👥📲 Instagram - https://www.instagram.com/electrician_u Discord - https://discord.gg/7ykYfbh Facebook Page - https://www.facebook.com/theelectricianu Facebook Group - https://bit.ly/2tz7eQh TikTok - https://www.tiktok.com/@electricianu Contactors and relays are simply switches. They differ from a standard switch, however, by being able to be controlled with electrical current rather than your finger. Both operate with a coil on the inside that, when energized, sucks contacts closed or snaps them open. It would be as if you were able to zap a normal light switch with a bolt of lightning to get it to change states....kind of. Both relays and contactors are also multi-pole switches. This means that they can control several circuits, rather than just one like a normal single-pole switch would do. A typical 8-pin cube relay can control 2 circuits, while an 11-pin can control 3. General-use contactors can control anywhere from 2-4 whereas lighting contactors can control from 6-12 circuits/loads. All with the flip of a single action (bump of current). What makes them different are a few things. First off, relays are typically lower voltage applications as well as lower-current applications. Relays you may come across could have coil voltages of anywhere between 12v and 240v on average, and can control loads in the 5-15amp range. Contactors tend to be more stout and can handle higher amperage through the coils and contacts. You could see coil voltage ratings between 120v-480v, and contacts around 30-50amps on average.
