Description

The KSD302 is a bimetallic disc thermostat, a robust electromechanical switch that opens or closes a circuit in response to temperature changes. The bimetallic element, housed within a ceramic insulator, deflects at its calibrated setpoint (60°C), causing the normally closed (NC) contacts to snap open, interrupting power to the connected load. This provides fail-safe overheat protection or basic temperature regulation.

Its ceramic construction ensures excellent electrical isolation and withstands high ambient temperatures. With a direct switching capacity of 16A at 250V AC, it is suitable for controlling heating elements, motors, or transformers without requiring an external relay in many applications, simplifying system design and reducing cost.

Key Features

  • Bimetallic Snap-Action Mechanism: Provides reliable, repeatable switching with a clear audible click and hysteresis to prevent contact chatter.
  • High-Power Switching: Rated for 16A resistive load at 250V AC, enabling direct control of significant loads.
  • Ceramic Insulation Body: Offers superior dielectric strength, flame resistance, and long-term stability under thermal cycling.
  • Normally Closed (NC) Configuration: Circuit is closed at room temperature and opens upon reaching the 60°C setpoint, ideal for safety cut-off applications.
  • Fixed Calibration: Factory-set trip point eliminates the need for user calibration, ensuring consistent performance.
  • Compact & Mountable Design: Features mounting holes for secure installation in appliances, enclosures, or on heat sinks.

Applications

  • Over-temperature protection in electric water heaters, coffee makers, and kettles.
  • Temperature regulation in incubators, soldering irons, and small space heaters.
  • Thermal cut-off safety device in power supplies, transformers, and battery chargers.
  • Appliance control in hair dryers, food warmers, and dehumidifiers.

Frequently Asked Questions

What does 'Normally Closed (NC)' mean for this thermostat?

In its normal state (below 60°C), the switch contacts are closed, allowing current to flow. When the sensing temperature reaches or exceeds the 60°C setpoint, the bimetallic disc snaps and opens the contacts, breaking the circuit. This NC configuration is standard for safety cut-off applications.

Can this KSD302 switch control a DC load, or is it AC only?

The 16A/250V rating is specified for AC resistive loads. For DC loads, the switching capability is significantly lower due to the difficulty of extinguishing a DC arc. It is not recommended for DC switching without detailed contact derating and possibly an external arc suppression circuit.

How do I install and wire this thermostat switch?

Mount the thermostat securely using its provided holes, ensuring good thermal contact with the surface whose temperature you need to monitor. Wire it in series with the load (e.g., a heating element) and the power source. The switch has two terminals; polarity does not matter for an AC circuit. Ensure wiring complies with local electrical codes for the current involved.
