Description

The KSD301 is a fixed-temperature, bimetallic thermal switch housed in a ceramic insulator. It operates as a normally closed (NC) switch, remaining conductive until the calibrated setpoint of 60°C is reached, at which point the internal bimetallic disc snaps open, breaking the circuit to protect the connected system.

Its ceramic construction provides excellent electrical isolation, high dielectric strength, and long-term stability under thermal cycling. The device is designed for direct series connection with loads up to 10A, eliminating the need for auxiliary relays in many applications, making it a cost-effective and reliable solution for basic thermal protection.

Key Features

  • Fixed 60°C (±5°C typical) trip temperature for consistent protection.
  • High-current bimetallic snap-action mechanism ensures reliable, fast switching.
  • Ceramic housing offers superior insulation, flame resistance, and heat dissipation.
  • Normally Closed (NC) configuration is ideal for safety cutoff circuits.
  • Compact and lightweight design facilitates installation in space-constrained areas.
  • Suitable for a wide range of voltages up to 250V AC/DC.
  • Rugged construction for long service life in demanding thermal environments.

Applications

  • Over-temperature protection in coffee makers, kettles, and small kitchen appliances.
  • Thermal cutoff for transformers, power supplies, and battery chargers.
  • Safety switch in incubators, terrarium heaters, and low-power heating elements.
  • Temperature monitoring in motor windings and electronic enclosures.

Frequently Asked Questions

What does Normally Closed (NC) mean for this thermal switch?

Normally Closed (NC) means the switch contacts are closed, allowing current to flow, at temperatures below its setpoint. When the sensing temperature reaches 60°C, the internal bimetallic element snaps open, breaking the circuit to stop current flow and provide over-temperature protection.

Can I use this switch to control a 120V AC heater directly?

Yes, provided the heater's current draw does not exceed the switch's 10A rating. The switch is rated for 250V AC/DC, so a 120V AC load is well within its voltage specification. Always ensure your load's maximum operating current is below 10A for safe and reliable operation.

Is the 60°C trip temperature adjustable?

No, the KSD301 is a fixed-temperature switch. Its bimetallic disc is factory-calibrated to snap open at approximately 60°C (with a typical tolerance of ±3-5°C). For an adjustable setpoint, you would require a different device, such as an electronic thermostat module.

How do I wire this two-terminal thermal switch?

Wire the switch in series with the load (e.g., heating element) and the power source. Since it is Normally Closed, it will pass power to the load until its setpoint is reached. Ensure connections are secure and the ceramic body is not subjected to mechanical stress or moisture incompatible with its insulation rating.
