KSD302 Thermal Switch, 16 A 250 VAC Manual Reset Thermostat

The KSD302 is a reliable, snap‑action, manual‑reset thermal switch that protects electrical circuits by mechanically breaking the connection when temperatures exceed a preset threshold. Designed as a normally closed device, it opens at to interrupt the circuit, and requires manual resetting once the temperature has dropped below its reset point. Rated for up to 16 A at 250 VAC, this compact thermostat is a simple and effective thermal safety device commonly used in household appliances, coffee makers, soldering irons, HVAC equipment, and DIY protection circuits.

Key Features:

• Precise thermal cutoff (±5 °C)—cutting power when exceeded to protect against overheating.
• High current capacity, supporting up to 16 A at 250 VAC, suitable for demanding resistive loads.
• Manual reset functionality—forces user intervention after a trip, ensuring safe diagnostics before reactivation.
• Snap‑action bimetal design—quick response to temperature changes and reliable open/close switching.
• Compact, easy mounting—available in surface or stem mount formats with fast-response terminals.
• Durable construction and long life—capable of handling over 30,000 cycles and built to standards ensuring longevity
