Hazardous-Location Motor Starters

Available2 products
Hazardous-location motor starters are electrically operated switches that provide overcurrent protection and control of power connections in environments where the possibility of flammable gases, vapors, or liquids, ignitable fibers or flyings, or combustible dust may exist under normal and abnormal conditions. Also known as hazardous-location magnetic motor starters, they have location ratings that classify their designated operating environment and must be mated with compatible, hazardous-location devices to comply with safety standards. Motor starters combine contactors and overload relays to turn high-current circuits on and off and help protect downstream connections like motors, machinery, and electrical systems from damage caused by overheating, low voltage, and overcurrent.

Enclosed Non-Reversing Starters with Thermal Overloads

Enclosed Non-Reversing Starters with Thermal Overloads

These non-reversing hazardous-location motor starters with thermal overloads have enclosures that protect the motor starter and other internal components from impacts, debris, and dust. Non-reversing motor starters connect and disconnect power to motors and other high-current equipment and machinery in a single direction. Thermal overloads, also known as heaters, prompt motor starters to break electrical connections with downstream equipment once a set temperature is reached to protect connected loads from overheating and causing damage. They contain either bimetallic strips or melting alloy solder materials. When the current exceeds a predetermined threshold and temperatures rise, the material bends or liquefies, causing the thermal unit to break the circuit and cause the motor starter to break its power contacts. As the materials cool down, they will return to their normally closed position and the circuit can be reset automatically or manually.
