Nema rated classes for overload relay

WebNEMA AC/DC Contactors. Our Bulletin 300 NEMA contactors and motor starters provide a space-saving and cost-effective alternative for applications that require NEMA-rated motor control. Based on our IEC contactor design, these NEMA-rated products are compatible with a wide range of accessories and solid-state overload relays. WebAn overload relay is a device that protects an electric motor against overloads and phase failure. It senses the overloading of the motor and interrupts the power flow to the motor, thus protecting it from overheating and winding damages. Apart from overloads, it can also protect the motor from phase loss/ failures and phase imbalance.
