Description

The KSD301 thermostat utilizes a bimetallic disc mechanism that snaps between two states at a precise calibration temperature. When the ambient temperature reaches its 130°C set point, the disc deflects, instantly closing the normally open contacts to complete a circuit, typically to shut off a heating element. This provides a failsafe, mechanical method of temperature regulation without requiring external power.

Encased in Bakelite, the switch offers excellent electrical insulation and resistance to heat, moisture, and mechanical stress. Its simple two-wire connection and fixed trip point make it an ideal, cost-effective solution for over-temperature protection in devices like electric kettles, coffee makers, water heaters, and industrial machinery where electronic control is unnecessary or undesirable.

Key Features

  • Fixed 130°C (±5°C) bimetallic snap-action mechanism for reliable tripping.
  • High-current capacity: 10A at 250V AC/DC for direct load switching.
  • Normally Open (NO) contact design for safety-cutoff applications.
  • Robust Bakelite housing ensures electrical safety and durability.
  • Maintenance-free operation with a long mechanical lifespan.
  • Compact form factor (approx. 9 x 6 x 2 cm) for space-constrained installations.
  • Widely compatible with standard appliance and industrial control wiring.

Applications

  • Over-temperature protection and control in electric water heaters and kettles.
  • Temperature regulation in coffee makers, rice cookers, and other small appliances.
  • Safety cutoff for heating elements in industrial equipment and machinery.
  • Thermal management in power supplies, transformers, and battery chargers.
  • Auxiliary temperature monitoring in HVAC systems and fan controllers.

Frequently Asked Questions

What is the trip temperature and tolerance for this KSD301 thermostat?

This KSD301 thermostat has a fixed trip point of 130°C. The typical manufacturing tolerance for this type of bimetallic switch is approximately ±5°C, meaning it will actuate between 125°C and 135°C. It is a single, factory-set point and is not user-adjustable.

How do I wire this Normally Open (NO) thermostat?

Wire the two terminals in series with the load (e.g., a heating element) and power source. In its normal state below 130°C, the circuit is open and current cannot flow. When the sensed temperature rises to the trip point, the internal bimetallic disc snaps, closing the contacts to complete the circuit and typically de-energize the heater.

What is the maximum electrical load this switch can handle?

This thermostat is rated for 10 Amps at up to 250 Volts, either AC or DC. This allows it to directly switch significant resistive loads like heating elements without requiring an external relay. Do not exceed these ratings to ensure safe operation and prevent contact welding or failure.

Is the Bakelite housing safe for high-temperature applications?

Yes, the Bakelite (phenolic resin) housing is specifically chosen for its excellent electrical insulation properties and thermal stability. It can withstand continuous operation at temperatures up to and beyond the 130°C trip point, ensuring safe containment and preventing electrical leakage or short circuits.
