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.


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.
