  22. Open Contactors & Starters

  23. What is the Difference: Between A Short Circuit & An Overload ? Overload Relays

  24. What Is A Short Circuit? An Extreme Amount Of Current Usually Caused By A Fault To Another Phase Or To Ground. Fault Currents Can Exceed Several Thousand Amps For A Very Short Period Of Time Which Can Cause Very Extensive Equipment Damage. Fault Currents May Even Reach Up To 200,000 Amps On Some Systems. Overload Relays

  25. What Is An Overload? 1. An Operating Condition Where The Load Current Exceeds Normal Operation. 2. A Motor That Is Overloaded May Draw 6 Times Its Normal Operating Current (Full Load Current). 3. An Overload For Even Several Minutes May Cause Severe Motor Damage. Overload Relays

  26. What Are The Differences Between … A Fuse Or A Circuit Breaker And An Overload Relay? Overload Relays

  27. Short Circuit Protection Devices Fuses - One Time Use Only Magnetic Circuit Breakers - Reusable After Reset Overload Protection Devices Time Delay Fuses -One Time Use Only Overload Relays- Able To Reset ThermalMagnetic Circuit Breakers- Also Able To Reset Overload Relays

  28. How Overload Relays Work Monitors Over-current Condition On Motor Power Leads Indirectly Thermal Type Overload Relay Directly Magnetic or Electronic Type Overload Relay Turns Off Control Circuit During Overload Condition OL Relay NO Contact Turns Off Motor Starter Coil Circuit Overload Relays
