Thermal Fuse, EYP Series
Compact, insulated type with excellent thermal responsiveness.Can be mounted without insulation or protection even in cramped spaces.
Undergoes minimal change over time; functions when an abnormality occurs, and does not reset.
Formed by a proprietary flanging process, the lead has good mechanical strength and enables easy mounting.(axial lead type only)
