Safety Cut Out

Safety Cut Out

Expo safety cutout is the most accurate and long lasting thermal cutouts. These are the open construction air sensing units. These are used in hair curlers, hair driers, heat convectors, cloth driers, fan heaters etc. These basically regulate the air temperature.

Operation

The thermal cutouts operate on the principle of thermal expansion. The contacts are normally closed and as soon as the fixed temperature is reached the contacts open and thus stop the mains supply. When the temperature falls by the differential the contacts join together and the mains supply to the appliance is restored.

Physical Characteristics

This is a small unit with a plastic body. It consists of two terminals on side of the plastic body and a fin with silver contacts on the other side. It is caused inside a highly insulating and heat resistant phenolic cover.

Fixing

The unit consists of two holes for the mounting. It should be fixed in such a way that the fin portion is directly in the path of the hot air. It has space type terminals for the connection.
