Hazardous-Location Manual Motor Starters

Available2 products
Hazardous-location manual motor starters are manually operated motor controllers that provide control of electrical 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. They have location ratings that classify their designated operating environment and must be mated with compatible, hazardous-location devices to comply with safety standards. Manual motor starters turn circuits on and off to small motors, machinery, and electrical systems and help protect them from damage caused by overheating, low voltage, and overcurrent. These manually operated motor starters combine contactors, overload relays, and disconnect switches to connect and disconnect electrical loads safely.

Enclosed Non-Reversing Starters with Thermal Overloads

Enclosed Non-Reversing Starters with Thermal Overloads

These non-reversing hazardous-location manual motor starters with thermal overloads have enclosures that protect their 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.
