Thermal Overload Protectors | Switch with NEMA 1 Enclosure Rating | Switch with NEMA 12 Enclosure Rating |
Combine a switch with a thermal overload element to build a starter that can handle high-current-rated motors. All are housed in a durable steel enclosure. They’re also known as NEMA starters.
Thermal overload elements shut motors off if current exceeds the full-load current rating. Three elements are required. To Order: Please specify the full-load current rating of your motor. If the full-load current rating is not shown on the motor’s faceplate, estimate the current rating (given the motor’s power and voltage).
NEMA 12 Enclosure Rating—NEMA 12 rated switches are protected from oil/coolant dripping.
