NTC Thermistors

ATC Semitec stocks an extensive range of auto-reset, manual reset and self-hold thermal protection devices from some of the world’s leading manufacturers such as PEPI, ASAHI, SEFUSE, EAW and SEKI.

Thermal protectors are used as safety mechanisms which will protect your products from overheating in the result of an abnormal operating condition.  The thermal cut-outs will protect against an over-temperature situation which could ultimately help to prevent fires or major damage to electrical components or appliances.

ATC Semitec stocks a comprehensive disc thermostat range from leading manufacturers Asahi Keiki and EAW.

Snap-action 1/2″disc bi-metal thermostats (or button thermostats) provide very reliable, cost-effective temperature control and thermal protection for domestic appliances and electronic circuits with a choice of manual or automatic reset available. These thermal switches can be supplied with tight tolerances and narrow differentials to make very effective thermostats; or they can be calibrated with wide differentials to provide over-temperature protection as either a thermal cut-out or a thermal limiter.

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.
