RD Series Mounted in an insulating ceramic base, a one shot, hi-limit with conﬁgurations to suit your requirements... RD Series Tear Drop Style The TCO responds to temperature by interrupting an electrical circuit when the operating and /or environmental temperature exceeds the thermal rating of the fuse. This is accomplished when the organic pellet experiences a phase change, allowing the spring activated contacts to permanently open the circuit.

Installation The performance of the Elmwood thermal cut offs requires proper handling during installation for it to operate in its intended manner. These instructions are intended to be used to reduce the risk of malfunction of the thermal cut offs which may result from improper installation during forming of leads, splicing, welding and soldering. 1. BENDING LEADS Care should be taken when forming the Thermal Cut Offs (TCO) leads.
