Description

The KSD301 is a bimetallic snap-action thermostat that opens or closes an electrical circuit based on a preset temperature threshold. The bimetallic disc deforms with temperature change, triggering a mechanical snap-action switch for reliable, repeatable operation at the calibrated setpoint of 50°C.

Housed in a Bakelite case, the device offers good electrical insulation and resistance to moderate heat. The normally closed (NC) configuration means the circuit is complete at temperatures below the setpoint and opens upon reaching 50°C, making it ideal for cut-off applications in heaters, coffee makers, or as a safety device.

Key Features

  • Fixed Temperature Actuation: Pre-calibrated to switch at 50°C with a typical tolerance of ±3-5°C.
  • Robust Electrical Rating: Handles up to 250V AC and 10A, enabling direct control of significant loads.
  • Durable Insulating Housing: Bakelite construction ensures electrical safety and thermal stability.
  • Reliable Snap-Action Mechanism: Bimetallic disc provides a quick, positive switch action for long life and arc suppression.
  • Simple Two-Wire Installation: Easy integration into series circuits for temperature-based power control.
  • Compact & Lightweight: Minimal footprint and a weight of approximately 3 grams for space-constrained applications.

Applications

  • Over-temperature protection cutoff in electric water heaters, kettles, and small appliances.
  • Temperature regulation in incubators, terrariums, or simple environmental chambers.
  • Safety switch in power supplies, transformers, or battery chargers to prevent overheating.
  • Thermal control in DIY soldering stations or 3D printer heated beds.
  • Basic on/off control for auxiliary heating elements in automotive or industrial contexts.

Frequently Asked Questions

What is the switching action of this KSD301 thermostat?

This is a Normally Closed (NC) switch. The contacts are closed, allowing current to flow, when the temperature is below its 50°C setpoint. When the sensed temperature reaches 50°C, the internal bimetallic disc snaps, opening the contacts and breaking the circuit.

What is the maximum electrical load I can connect?

The thermostat is rated for 250 Volts AC and a maximum current of 10 Amps. Do not exceed these ratings. It is suitable for directly switching resistive loads like heating elements within this power envelope (up to 2500W at 250V).

How do I install and wire this temperature switch?

Install the thermostat in direct thermal contact with the surface or medium you wish to monitor. Wire it in series with the load (e.g., heater) and power source using its two terminals. Ensure the Bakelite body is securely mounted and not subjected to mechanical stress on the terminals.

Can the setpoint temperature be adjusted?

No, the KSD301 model features a fixed, factory-calibrated setpoint of 50°C. It is not user-adjustable. For a different trip temperature, you would need to select a different model with the corresponding fixed setpoint.
