Product Identity
The Unique-Bargains KSD301 is a normally-closed thermal switch rated for 180°C or 356°F. It suits technicians repairing household appliances that require automatic over-temperature protection.
Functional Impact
The ceramic core opens the circuit when the mounting surface reaches the set temperature and resets once it cools. Rated at 250V 10A with 50M Ohm circuit resistance and 100M Ohm insulation resistance, it restores power without manual intervention.
Installation Check
Verify that the 3.3 x 2 x 1.1 cm metal and ceramic body fits the appliance cavity. Confirm the circuit operates within 250V 10A limits and that the mounting surface will reach 180°C during a fault condition.

Questions about this item
Will the ceramic core of the KSD301 thermal switch need periodic replacement?
The ceramic core is a fixed part of the switch assembly and is not designed to be replaced separately. If the switch fails, the entire unit is replaced.
At what temperature does the NC contact open during continuous operation?
The switch opens when the mounting surface reaches 180°C (356°F) and automatically resets when the temperature drops.
How much heat does the switch body generate when conducting 10 A at 250 V all day?
The circuit resistance is rated at 50 MΩ, so the switch body generates negligible heat while conducting within its 10 A / 250 V rating.
