Steatite

KER 220 - Group in accordance with IEC 672-3 - C 220; Steatite ceramics - Silicate with at least 70% of talc.

Material for insulators and power supply parts working at temperatures that do not exhibit higher jump changes than 70°C; porous with high mechanical bending strength under 80 MPa.

E.g.: fuse bodies, switch bases, fuse bases, holders, thermostat parts, bushings, insulating beads, ceramic holders, bases, sockets, plate heat radiators.
