One-shot thermal fuse link – backup overheat protection in electric furnaces and air handlers. It never resets: once open, the heater circuit stays dead until the link is replaced, and a blown link means something else (restricted airflow, a failed blower) caused the overheat, so find that fault before fitting a new one. No datasheet is published, so amperage and voltage are unconfirmed. Fit only an identical temperature rating. Specifications from our own stock records. The manufacturer does not publish a public page for this item.
