TUV UL 250V 16A FSKH Ceramic Bimetal Thermostat Fuse Types Over Temperature Switch

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Over-temperature Protection: Automatically interrupts electrical circuits when temperature exceeds predefined thresholds, safeguarding equipment and systems from overheating.
  • Precise Temperature Control: Adjustable temperature settings (via KSD301 design) enable customization for specific applications, ensuring optimal thermal regulation in heating/cooling systems.

Key features

  • 1. Ceramic Body for Enhanced Thermal Stability

    • With a ceramic body, you can ensure reliable operation in extreme temperature fluctuations, outperforming traditional metal-bodied switches prone to thermal expansion.

  • 2. Adjustable Temperature Thresholds for Precision Control

    • With customizable temperature settings, you can optimize activation/deactivation points to suit specific applications, unlike fixed-temperature alternatives.

  • 3. High-Power Compatibility for Demanding Applications

    • With a 250V/16A rating, you can handle heavy-duty systems, surpassing lower-rated switches (e.g., 125V/10A) in commercial or industrial settings.

  • 4. Versatile Mounting and Design for Universal Integration

    • With a compact, surface-mount design, you can easily integrate the switch into tight spaces or custom systems, unlike bulkier competitors.

  • 5. Comprehensive Safety and Environmental Compliance

    • With TÜV, UL, CB, RoHS, and REACH certifications, you can meet global safety and eco-friendly standards, exceeding basic compliance requirements.
