Description

The KSD302 is a bimetallic disc thermostat housed in a durable ceramic body. The device operates on a snap-action principle: when the ambient temperature reaches its calibrated setpoint of 100°C, the internal bimetallic disc deforms, causing the normally open (NO) contacts to close (or, conversely, a normally closed configuration to open, depending on wiring). This action directly controls the connected circuit without requiring an external power supply.

Its ceramic construction provides excellent electrical isolation, flame retardancy, and resistance to thermal shock, ensuring long-term reliability in demanding environments. The 250V 10A rating allows it to be used as a primary safety cut-off or control element in various resistive heating applications and power equipment.

Key Features

  • Bimetallic Snap-Action Thermostat: Provides reliable and precise switching at the 100°C calibration point.
  • Ceramic Encapsulation: Offers high dielectric strength, thermal endurance, and mechanical protection.
  • High Load Capacity: Directly switches up to 10A at 250V AC or DC, eliminating the need for a relay in many circuits.
  • Normally Open Configuration: Contacts remain open under normal conditions, closing upon reaching the temperature threshold.
  • Compact and Lightweight Design: Facilitates easy mounting in confined spaces within appliances or control panels.
  • Maintenance-Free Operation: Sealed construction ensures consistent performance without requiring calibration.

Applications

  • Over-temperature protection in electric kettles, coffee makers, and water heaters.
  • Temperature regulation in incubators, soldering stations, and laboratory heating equipment.
  • Safety cut-off for transformers, power supplies, and battery chargers.
  • Thermal control in HVAC components, fan controllers, and de-icing systems.
  • Appliance safety compliance for consumer electronics and white goods.

Frequently Asked Questions

What is the switching action of this KSD302 thermostat?

This KSD302 model is configured as Normally Open (NO). This means the electrical contacts are open under normal (cool) conditions. When the temperature at the sensor reaches the calibrated setpoint of 100°C, the internal bimetallic disc snaps, closing the contacts to complete the circuit.

Can this thermostat switch DC loads as well as AC?

Yes, the 250V 10A rating is typically applicable for both AC and DC loads. The bimetallic switching mechanism is not polarity-sensitive. Ensure the voltage and current of your DC circuit do not exceed these specified limits for reliable operation and contact life.

How do I install and wire this temperature switch?

Installation is straightforward. Mount the thermostat body securely to the surface whose temperature you wish to monitor, ensuring good thermal contact. Connect the two terminal wires in series with the load (e.g., heater) and power source. No external power is required for the switch itself to operate.
