Bi-metallic thermal overload relay

The bi-metallic thermal overload relay is the most widely used in industry and provides a high level of protection against small or prolonged overload conditions.The bi-metallic thermal overload relay is the most widely used in industry and provides a high level of protection against small or prolonged overload conditions. They may be used on a.c or d.c systems and generally feature: Three pole operation and protection Ambient temperature compensation, so that temperature fluctuations do not affect their overall performance Single phase protection, this prevents the associated motor running in a single phase condition Manual or automatic resetting A graduated scale in “motor FLC” thus allowing the relay to be set according to the “full load current “ as shown on the motor plate.
