Description

The KSD301 is a bimetallic disc thermostat housed in a ceramic body, providing a reliable and cost-effective solution for over-temperature protection. The normally open contacts close when the ambient temperature reaches the calibrated set point (60°C), completing a circuit to activate a fan, heater, alarm, or cut power to a load. Its robust ceramic construction offers excellent electrical isolation and resistance to arcing, making it suitable for mains voltage applications.

This mechanical switch requires no external power, offering a failsafe, purely physical response to temperature changes. It is designed for surface mounting in appliances, power converters, battery chargers, and industrial control panels where a simple, maintenance-free thermal cutoff is required. The snap-action mechanism ensures a clean, quick make/break contact to prevent chatter and prolong switch life under its 10A rating.

Key Features

  • Ceramic body providing high dielectric strength and heat resistance.
  • Bimetallic snap-disc actuator for precise, repeatable switching at 60°C.
  • Rated for 250V AC/DC operation handling up to 10A resistive loads.
  • Normally Open (NO) contact configuration for safety-cutoff applications.
  • Compact, sealed design suitable for integration into enclosed assemblies.
  • No external power or signal conditioning required for operation.
  • High-value build for cost-sensitive thermal management solutions.
  • Wide compatibility with common appliance and industrial control voltages.

Applications

  • Over-temperature protection in power supplies, transformers, and battery chargers.
  • Thermal cutoff safety switch in coffee makers, water heaters, and small appliances.
  • Temperature-activated fan control in electronic enclosures and AV equipment.
  • Simple thermal regulation in incubators, terrariums, and DIY heating projects.
  • Failsafe circuit interruption in motor drives and industrial control cabinets.

Frequently Asked Questions

What is the switching action of the KSD301 thermostat?

The KSD301 is a Normally Open (NO) bimetallic thermostat. Its contacts are open at room temperature and will physically close (completing the circuit) when the sensed temperature rises to its calibrated set point of 60°C. Upon cooling below the set point, the contacts open again.

What is the maximum electrical load this switch can handle?

This thermostat is rated for a maximum of 10 Amperes at 250 Volts AC or DC. This rating is typically for resistive loads; for inductive loads (like motors or solenoids), derating or the use of an arc-suppression circuit is recommended to prolong contact life.

How do I install and wire this temperature switch?

Installation is straightforward. The switch has two terminals. Wire it in series with the load (e.g., a heater or fan) and the power source. Ensure the ceramic body is in good thermal contact with the surface or medium you wish to monitor. The switch itself requires no separate power supply.

Can the 60°C set point be adjusted?

No, the KSD301 is a fixed-set-point, factory-calibrated mechanical thermostat. The bimetallic disc is calibrated to snap at 60°C, and this setting is not user-adjustable. For adjustable control, a separate electronic temperature controller and sensor would be required.
