PEPI Bimetal Thermal Fuses

ATC Semitec’s range of ‘single-shot’ bimetal thermal fuses or cut-offs from PEPI offer superior and reliable thermal protection particularly at high temperatures, especially above 200°C where pellet fuses can often be less reliable. They have the benefit of offering a wider range of temperatures between the points of opening and closure.

Ceramic versions are also available offering settings up to 280°C.

These high temperature thermal fuses from PEPI (Portage Electric Products Inc) use unique bimetal technology which stops them from resetting, even at temperatures as low as -35°C. They do not suffer from thermal ageing like eutectic fuses, so can be more closely coupled to the appliance or heater providing fast accurate protection.

These fuses are highly versatile in how they can be tailored to meet your individual application- including operating temperature ranges, lead lengths, added terminals, insulting sleeves etc.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.

    • Contact rating 15A/250VAC (or 1A/50VDC option)
    • C-UL and TuV approvals
    • Ideal for office automation products, home and personal care small appliances

  • PEPI H1 One-Shot Fuses
    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 H3 Fast Response One-Time Fuse
    PEPI H3 Fast Response One-Time Fuses

    A fast response snap-action single-operation thermal control, which is suitable for high temperature applications. Even faster response is achieved by using exposed bi-metal elements.

    • Suitable for high temp application
    • Temperature range: 130°C to 260°C
    • Rated to 10A/240VAC

    Also available as:

  • PEPI H8 High Temp Fuses
    PEPI H8 High Temperature One-Shot Fuses

    PEPI H8 High Temperature One-Shot Fuses operate as a high limit, single operation type control. The ceramic case isolates them from the electrical circuit.

    • Ultra-fast response times
    • Ceramic case allows operation up to 280°C
    • Temperature range: 250°C to 280°C
  • PEPI J2 Snap Action Bi-Metal Fuse
    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
