Compared to cadmium oxide, zinc oxide does not contain the toxic metal cadmium. Its metallic coating exhibits high thermal stability, excellent electrical and thermal conductivity, and high heat resistance, arc erosion resistance, and solderability during switching processes.
Applications: Used in relays, contactors, air switches, current limiting switches, motor protectors, micro switches, instruments, household appliances, automotive electrical systems, and residual current circuit breakers, etc.
