Description

The KSD301 is a bimetallic disc thermostat that provides precise, fixed-temperature switching at 60°C. When the ambient temperature reaches the calibrated setpoint, the internal bimetallic disc snaps, mechanically closing the normally-open contacts to complete a circuit. This action is ideal for activating cooling fans, cutting power to heating elements, or triggering alarms in over-temperature protection scenarios.

Encased in flame-retardant Bakelite, the switch offers excellent electrical insulation and resistance to heat aging. Its robust construction ensures reliable performance across thousands of cycles in environments such as electric kettles, coffee makers, battery chargers, and small motor overload protection systems. The screw terminals facilitate secure wiring connections for mains-voltage applications.

Key Features

  • Bimetallic Snap-Action Mechanism: Provides Sharp Microelectronics, reliable contact switching with minimal contact bounce and high repeatability.
  • Fixed Calibration Point: Pre-set to actuate at 60°C (±5°C typical), eliminating the need for user adjustment.
  • High-Current Capacity: Handles up to 10A at 250V AC/DC, suitable for directly switching small heaters, motors, or solenoids.
  • Bakelite Insulation: Flame-retardant phenolic housing ensures electrical safety and long-term stability at elevated temperatures.
  • Normally Open Configuration: Contacts remain open under normal conditions, closing upon temperature rise to activate a connected load or alarm.
  • Compact & Lightweight: Minimal footprint and 3g weight allow for easy mounting in space-constrained applications.

Applications

  • Over-temperature protection in small appliances (e.g., coffee makers, electric kettles, rice cookers).
  • Thermal cutoff for battery charging systems and power supply units.
  • Temperature control in incubators, terrariums, and DIY heating pads.
  • Safety interlock for motor overload protection in fans, pumps, and small tools.
  • Auxiliary temperature switching in HVAC control panels and ventilation systems.

Frequently Asked Questions

What is the switching action of this KSD301 thermostat?

The KSD301 is a normally-open (NO) bimetallic thermostat. Its contacts are open at temperatures below 60°C. When the sensing temperature rises to the calibrated setpoint of 60°C (±5°C), the internal bimetallic disc snaps, mechanically closing the contacts to complete the circuit.

Can this switch handle mains voltage and inductive loads?

Yes, it is rated for 250V AC/DC and 10A. This makes it suitable for directly switching mains-powered resistive loads like heating elements. For inductive loads (motors, solenoids), it is recommended to use it within its rating and consider inrush current; for higher inductive loads, using it to trigger a relay is advised.

How do I wire and mount the KSD301 thermostat?

Connect your load and power source to the two screw terminals. Ensure the thermostat's metal sensing face is in good thermal contact with the heat source (e.g., attached with thermal adhesive or a clamp). Mount it securely using its mounting holes, avoiding stress on the terminals. The Bakelite housing provides electrical insulation.

Is the 60°C setpoint adjustable?

No, the KSD301 is a fixed-setpoint thermostat. The bimetallic disc is factory-calibrated to snap at 60°C with a typical tolerance of ±5°C. For adjustable temperature control, a separate potentiometer-based electronic thermostat module would be required.
