Organic Thermal-Link (OTCO) is defined as a non-resettable protective device, functioning one time only. It mainly consists of metal case, spring, conductive nail, sliding contact and thermal pellet. When the Thermal-Link senses abnormal heat and temp. reaches the predetermined fusing temp., thermal pellet melts and the conductive nail separates from the isolated lead with the assistance of the trip spring, thereby the circuit is disconnected.
SETsafe | SETfuse Organic Thermal-Link (OTCO) RK series Rated Functioning Temp. from 72 °C to 310 °C, Rated Current: 20 A, safety certification Includes UL, cUL, and complies with RoHS and REACH.
