NEMA Manual Motor Starters

Available35 products
NEMA manual motor starters are made to standards designated by the National Electric Manufacturers Association (NEMA). Manual motor starters open and close electrical circuits 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. NEMA manual motor starters have robust constructions that come in standard NEMA motor sizes and withstand harsh environments. They are serviceable with replaceable parts and have longer service lives than IEC manual motor starters.

Non-Reversing Starters with Thermal Overloads

Non-Reversing Starters with Thermal Overloads

These non-reversing NEMA manual motor starters with thermal overload relays connect and disconnect power to motors and other high-current equipment and machinery in a single direction. Thermal overload relays prompt motor starters to break electrical connections with downstream equipment once a set temperature is reached. The thermal units, also known as heaters, are made of either bimetallic strips or solder-type materials and change shape as electrical current increases and temperatures rise. As the material changes shape, it opens and closes contacts that signal motor starters to disconnect power and prevent connected loads from overheating and causing damage.

Enclosed Non-Reversing Starters with Thermal Overloads

These non-reversing NEMA manual motor starters with thermal overloads have enclosures that protect their internal components from impacts, debris, and dust.
