Unique-Bargains KSD301 65°C 10A 250V NO 6.3mm 2pcs electrical timer switch

SKU CH-PNWR-VGGJN MPN KSD301

A pack of two normally-open thermal switches that close at 65 °C, rated 10 A at 250 V with 6.3 mm right-angle pins and a 50,000-cycle contact life

  • Opens at 65°C for automatic over-temperature protection
  • 10 A 250 V rating handles high-power heating elements
  • 3 mm right-angle pins fit standard quick-connect terminals
  • Rated for 50,000 cycles for long service life
  • 2000 V AC dielectric strength prevents arc breakdown

Two-Pack Thermal Switches

This pack contains two KSD301 thermal control switches rated for 65°C operation. Each unit is a normally open contact that closes when the sensed temperature exceeds the set point. They are designed for temperature protection in household electric appliances such as water dispensers, coffee makers, and dryers.

Sustained Operation Behaviour

The contacts are rated for 10A at 250V and tested to withstand AC 50Hz at 2000V for one minute without breakdown or arc phenomenon. Mechanical life exceeds 50000 action cycles, indicating durability under repeated thermal cycling. The bimetal sensor provides stable, automatic reset performance over long service periods.

6.3mm Terminal Interface Limits

Each switch uses right-angle pins with a 6.3mm width for standard spade terminal connections. The normally open logic means the circuit remains broken until the 65°C threshold is reached. This fixed temperature and contact rating define the operational envelope; the switch cannot be adjusted for different trip points or higher current loads.

Highlights

Questions about this item

Does the 65°C KSD301 generate noticeable heat or draw extra power when it cycles continuously all day?

The switch itself consumes negligible power and adds no measurable heat; it simply opens or closes at the rated temperature.

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

You need matching 6.3 mm female spade terminals or a compatible terminal block rated for 250 V and 10 A.

Will the 50,000-cycle contact life hold up if I pair it with an older motor that spikes above 10 A on start-up?

The 10 A rating is the maximum continuous current; start-up surges above that can shorten the contact life below the rated cycles.
