SKU CH-ENEB-DBXVX MPN KSD301

Two normally-closed thermal switches open at 110°C, rated 10 A at 250 V with 6.3 mm pins and 50000-cycle life

  • Opens at 110°C to protect appliances from overheating
  • Rated 250V 10A for reliable high-current switching
  • 3mm pins fit standard spade connectors
  • Contact life exceeds 50000 cycles for long service
  • Withstands 2000V AC electrical strength without arc

Thermal Switch for Appliance Protection

The KSD301 is a normally closed thermal control switch designed to interrupt power when temperatures reach 110°C. It suits repair technicians and DIY users fitting safety cut-outs to heating elements in water dispensers, coffee makers, dryers and similar domestic appliances.

10A 250V Rating with 50000 Cycle Life

Each switch carries up to 10A at 250V, providing headroom for standard mains-powered heating circuits. The contact life exceeds 50000 operations, so the device remains reliable through repeated thermal cycling. It runs out of margin if the load exceeds the rated current or if the ambient temperature surpasses the 110°C trip point.

Snap-In 6.3mm Pins and Automatic Reset

The 6.3mm wide pins allow quick push-on wiring without soldering, speeding up installation in tight appliance chassis. An automatic reset function restores the closed contact once the temperature falls below the threshold, eliminating manual intervention. The double-metal snap-action mechanism ensures arc-free switching at AC 2000V dielectric strength.

Questions about this item

Will the KSD301 switch work with existing 250 V circuits that use 6.3 mm terminals?

Yes, the switch is rated for 250 V and 10 A, and its pins are 6.3 mm wide, matching standard quick-connect terminals.

How can I confirm the KSD301 opens at 110 °C after installation?

Apply heat until the switch reaches 110 °C; the normally-closed contacts should open, breaking the circuit, and close again when the temperature falls.

Does the package include mounting hardware or only the two KSD301 switches?

The box contains two KSD301 temperature control switches; no brackets, screws or wiring are supplied.
