Out of Stock

The KSD302 is a ceramic-bodied, snap-action thermal switch designed for reliable temperature control in electrical appliances. It operates as a normally open (NO) switch, closing at 100°C, and is rated for 250V AC and 16A loads, making it suitable for integration into heating elements, power tools, and small appliances.

Features

  • Ceramic housing for high thermal conductivity and electrical insulation.
  • Normally Open (NO) snap-action switch closes at the rated 100°C setpoint.
  • High current capacity of 16A at 250V AC for direct load switching.
  • Bimetallic disc actuator provides reliable, repeatable switching.
  • Compact and robust design for integration into appliances and industrial controls.

Description

The KSD302 is a bimetallic disc thermostat housed in a durable ceramic body. The ceramic material offers excellent thermal transfer from the monitored surface to the internal snap-action mechanism while providing high dielectric strength and flame resistance. The switch is in a Normally Open (NO) state at ambient temperatures and closes the circuit once the calibrated temperature of 100°C is reached, acting as a safety cut-off or control element.

This device is a non-adjustable, fixed-temperature switch designed for direct series connection with the load. Its 16A/250V rating allows it to control heating elements, motors, or transformers directly without requiring an intermediate relay in many applications, simplifying system design. The robust construction ensures stable performance across its operational lifespan.

Key Features

  • Fixed temperature setpoint of 100°C (±5°C typical).
  • Ceramic enclosure for superior electrical isolation and heat dissipation.
  • Bimetallic snap-action mechanism ensures quick, positive contact closure.
  • High-breaking-capacity contacts rated for 16A resistive load at 250V AC.
  • Designed for surface mounting with solder or screw terminals (configuration dependent).
  • Optimized performance-to-cost ratio for mass-produced appliance integration.

Applications

  • Over-temperature protection in electric kettles, coffee makers, and water heaters.
  • Thermal cutoff for motors in power tools, fans, and pumps.
  • Temperature regulation in soldering irons, glue guns, and small heating elements.
  • Safety interlock in transformers, power supplies, and battery chargers.
  • Appliance control in rice cookers, slow cookers, and other kitchen electronics.

Frequently Asked Questions

What does 'Normally Open (NO)' mean for this KSD302 switch?

The KSD302 is a Normally Open (NO) switch, meaning its electrical contacts are open at room temperature and below its setpoint. When the temperature rises to its calibrated 100°C trip point, the internal bimetallic disc snaps, closing the contacts to complete the circuit, which can be used to turn a device on or trigger a safety shutdown.

Can this switch be used to directly control a 1500W heating element?

Yes. At 250V, a 1500W heating element draws approximately 6A (1500W / 250V = 6A). This is well within the KSD302's 16A rating, allowing it to switch the load directly without an external relay. Ensure your operating voltage matches the 250V AC rating.

Is the 100°C setpoint adjustable?

No. The KSD302 is a fixed-temperature, non-adjustable thermostat. The bimetallic disc is factory-calibrated to snap at 100°C (± a typical tolerance of 3-5°C). For adjustable control, you would need a separate electronic temperature controller with a sensor and relay output.

How should I mount and wire this ceramic thermostat?

Mount the switch with its ceramic face in direct, firm contact with the heat source (e.g., a heating element surface or motor housing) using the provided mounting holes or adhesive. For optimal thermal transfer, use thermal paste. Connect the two solder lug or screw terminals in series with the load (e.g., the heating element) and the power source, observing the voltage and current limits.
