NEMA Overload Relays

0 products

Designed to meet the rigorous standards set by the National Electric Manufacturers Association (NEMA), NEMA Overload Relays are essential electromagnetic switches. They play a critical role in safeguarding motors, machinery, and high-voltage systems by detecting excessive current or phase failure and signaling contactors to de-energize circuits, thereby preventing overheating and damage. These relays are integral components in motor starter assemblies when paired with compatible contactors.
