Unique-Bargains KSD301 115°C 250V 10A NC 6.3mm 2pcs electrical timer switch

SKU CH-02Y0-Z5Q8W MPN KSD301

Pack of two normally-closed thermal switches that open at 115°C, rated 250V 10A with 6.3mm right-angle pins and 50,000-cycle life

  • Normally closed operation protects equipment at 115°C
  • 250V 10A rating handles demanding heating circuits
  • 3mm right-angle pins fit standard connectors
  • 50000-cycle contact life ensures long service
  • 2000V electrical strength prevents arc breakdown

115°C thermal cut-off switch

The KSD301 is a bimetallic temperature control switch that opens its contacts when the sensed temperature reaches 115°C. It is rated for 250V and 10A, making it suitable for mains-powered heating appliances. The normally-closed design provides fail-safe power interruption for over-temperature protection. Two switches are included in the pack.

Suits appliances needing automatic reset protection

This switch fits designs that require a self-resetting thermal cut-out at a fixed 115°C trip point, such as water heaters, coffee makers, dryers or motor windings. It is not suitable for circuits that need a lower or adjustable trip temperature, or for applications demanding a normally-open contact that closes on temperature rise. Buyers needing a manual-reset limiter or a different current rating should look elsewhere.

115°C fixed trip temperature

The single specification that decides fit is the 115°C action temperature; the switch opens at this point and automatically resets when the temperature falls. The 6.3mm right-angle pins and 50000-cycle contact life are secondary to this fixed thermal threshold. Confirm that your appliance requires exactly this trip point before fitting.

Questions about this item

Does the 10 A contact rating generate noticeable heat or power draw during continuous operation?

The switch is rated for 10 A at 250 V and designed for automatic reset with no arc phenomenon, so normal operation stays within its thermal limits.

What wiring or terminals must I already have to install the 6.3 mm right-angle pins?

You need mating 6.3 mm (0.25 inch) quick-connect terminals or a compatible connector block to accept the right-angle pins.

Will the 115 °C trip point work reliably with older heating elements that cycle above and below that temperature?

Yes, the normally-closed contact opens at 115 °C and automatically resets when the temperature falls, rated for more than 50,000 cycles.
