Ceramic Thermal KSD301 Switch Thermostat 16A 250V 90°C NC NO

HCET KSD301 Thermal Switch 16A 250V 90°C NC/NO Bimetal Thermostat with M4 Thread of Screw for Ovens Temperature Protection

The KSD301 is a precision-engineered snap-action bimetal thermostat designed for critical temperature control in high-current environments.

It utilizes a calibrated bimetal that automatically opens the circuit at 90°C (±5°C tolerance) and resets when the temperature drops to the set temperature,

ensuring fail-safe protection for 16A/250VAC systems. This NC (normally closed) device features corrosion-resistant M4 screw terminals

for reliability in demanding applications.

Product feature:

1. Cross-industry voltage durability
   16A operating current in 250VAC systems, 50Hz/60Hz grid-approved to serve OEM customers worldwide.
2. Military-Grade Startup Accuracy
   Bimetal repeatability after 100,000 cycles to ±3°C customized accuracy, better than ±5°C industry standard for medical sterilizer applications.
3. Vibration-proof M4 locking
   Customized M4 threaded fittings with brass terminals prevent loosening during installation in automotive engine compartments.
4. Customized -20°C to +280°C operating temperature range
