PEPI Probe Thermal Cut-Outs

PEPI thermal cutouts provide over-temperature control and thermal protection from 5°C to 200°C. PEPI protectors can be calibrated down to a ±5K tolerance and with a wide temperature differential, they offer a compact solution to solve over-temperature problems.  The latest PEPI FCP and PEPI ST01 thermal protectors offer combined thermal/current overload protection and can readily switch up to 8A/250VAC or 12A/24VDC.

One of PEPI’s neatest designs is an integral “self-hold” thermal and current sensitive cut-out, the model JS. The PEPI JS protector latches open after tripping and is then reset remotely, thus offering the same benefit as fitting a manual-reset cut-out but without the disadvantage of having to access it.

All PEPI thermal protection devices carry a range of international safety approvals (e.g. VDE, UL, CSA) to the latest EN and IEC standards.

  • PEPI J Series Bimetal Thermal Cut-Outs

    PEPI J snap-action thermal cut-outs are available with a range of bimetals to alter their current sensitivity.  Thus they can be used for both over-temperature and over-current protection.

    • Temperature range: 60°C to 160°C
    • Contact ratings; 15A/250VAC or 10A/12VDC
    • Various levels of current sensitivity
  • PEPI J(S) Self-Hold Thermal Cut-outs

    The PEPI J(S) is a snap-action, self-hold thermal protector that has a built-in heating resistor to stop the PEPI from auto-resetting.  This offers a superior level of protection compared with auto-reset cut-outs.

    • Built-in self-hold resistor, remote reset
    • Suitable for 240VAC or 120VAC operation
    • Nominal temperature settings from 60°C to 160°C
  • PEPI FCP Thermal Cut-outs

    PEPI FCP (FC-P2D) thermal cut-outs have an isolated case with an automatic reset function.  With a wide differential, the PEPI FCP is ideal for protecting small appliances, electric motors, transformers, etc.

    • Temperature settings from 50°C to 130°C in 5K steps
    • Insulated PBT plastic housing
    • Compact design 4 x 7.5 x 15mm
  • PEPI F Snap-Action Thermal Cut-Outs

    The PEPI F snap-action thermal cut-out is a small, auto-reset thermal protector suitable for numerous applications.  Due to internal spacings, it can be used upto 277VAC in lighting protection applications.

    • Nominal temperature calibration 60°C to 150°C
    • Snap-action operation with a wide differential
    • Contact ratings up to 8A/250VAC & 5A/277VAC
  • Snap action thermal cut out, Brass casing
    PEPI ST01 Series Bimetal Thermal Cut Out

    The PEPI ST01 series is a snap-action, auto-reset thermal protector that will fit into the smallest of spaces.  It can be readily wound into electric motor windings to protect against over-temperature.

    • Nominal calibrations from 60°C to 160°C
    • Snap-action contacts with auto-reset function
    • Brass case provides good thermal conductivity
