Motogard - Over-Temperature Protection

Motogard Over-Temperature Protection Systems provide immediate overheating protection for: motors, equipment enclosures, semiconductor heatsinks, sleeve bearings, and other related machinery.

All Motogard systems fully conform to the NEC requirements for integral motor thermal protection.

Using Positive Temperature Coefficient (PTC) thermistors embedded in or in contact with the surface, the Motogard system is able to continually sense when the equipment exceeds the pre-selected temperature limits.

Motogard systems are recommended for applications requiring high reliability under conditions of heavy duty or severe ambient contamination. Minimum rif interference, absence of arcing, and maintenance-free long life are built into the Motogard systems.
