PEPI H9 Ultra Small Bimetal Thermal Fuse

These are the smallest bimetal thermal fuses available in the PEPI H range.  The strong phenolic resin case has very high heat resistance and so allows temperature calibrations upto 260℃.

The switching mechanism is a fast-response bimetal snap-action blade that once activated, will not reset even in ambients as low as -35℃.  So they are ultra reliable and have many benefits over conventional pellet-style fuses.

The PEPI H9 has a 15A/250VAC contact rating whereas the sister part PEPI H10 has a 1A/50VDC contact ratings.
