PEPI Thermal Protectors

PEPI thermal protectors from ATC Semitec offer superior and reliable over-temperature protection from 5°C to 200°C with current ratings up to 15A/250VAC.  Their neat design small package sizes help to protect circuits in the tightest of spaces.

PEPI bi-metal protectors can be supplied as automatic-reset limiters, self-hold cut-outs or even one-shot fuses offering different levels of safety depending on what the application or approval standard requires.  PEPI C and V thermostats are auto-resetting whereas the low-profile PEPI JS offers self-hold, non-resetting protection for both 240VAC and 120VAC.

PEPI J-2 and PEPI H bimetal fuses offer the ultimate in reliable thermal protection, with some ceramic versions offering over-temperature protection up to 280°C.

    PEPI H1 One-Shot Thermal Fuses

    The PEPI H1 is the lowest-profile, one-shot bimetal thermal fuse offering superior ultimate thermal protection up to 240°C.

    • Miniature size: 18 x 7 x 5 mm
    • Temperature range: 160°C to 240°C
    • Fast thermal response
    • Rating 10A/250VAC
  • PEPI J2 Snap Action Bi-Metal Fuse

    The PEPI J-2 is a snap action thermal fuse that functions as a non-resetting over-temperature control.  This single operation device performs like a conventional thermal fuse but with the reliability of the sensing element being 100% tested first.

    • Temperature range: 70°C~160°C
    • Contact rating: 15A/120VAC
