PEPI ST01 Series Bimetal Thermal Cut Out

The PEPI ST01 series is a snap-action thermal cut-out offering exceptional performance in an extremely small package.  The ST01 has a small, round low-profile design and so it fits neatly into the smallest of places.

Designed as an economical solution for use with transformers, electric motors and lighting ballasts, it can also be used as a general over-temperature sensor in heating and other electrical circuits.  Nominal factory calibrations are available from 60°C to 160°C in 5K steps.

The ST01 is available with a variety of lead-wire and insulating cap configurations to meet the requirements of different applications.  A self-hold model is also available for applications requiring an even higher level of protection.  An internal resistor heats up and holds the circuit open until power is disconnected.
