High current. Manual. Phenolic. Open on rise. 15 A/10 A. Silver/nickel-alloy contacts. Rivet sleeve. UL, CSA, VDE.
The 3455RM Series consists of a temperature-sensitive bimetal disc, electrically isolated from the switch, which actuates the normally closed contacts. The contacts open when the surface or ambient temperatures increase to the operating snap point of the calibrated disc. The circuit will stay open above room ambient temperature until the manual reset button is pressed. Response to temperature changes is extremely rapid due to the inherently low mass of the disc and the small size of the product.
