Motor Overload Relays and Thermal Units

Image 1

Motor overload relays and thermal units help prevent motor damage and extend motor life. Thermal units are for use in motor starters to help provide motor protection up to 266 full load amps. IEC overload relays help adjust the maximum current a motor is allowed to draw. Manual motor protectors can keep equipment from overheating and overloading. IEC delay timers can delay contactors or starters from turning on or off and have a time delay of up to 180 sec. NEMA overload relays can help protect against phase loss and phase imbalance, while manual motor protectors have electronic overload protection, provide minimum heat loss, and are suited to individual starting conditions.
