Product Overview

The HCET 3MP motor thermal protector is an intelligent electromechanical protection device engineered for demanding automotive and industrial applications. This UL-recognized component provides dual-mode protection through precise temperature monitoring (30-180°C ±5℃) and current overload detection (1-45A DC/AC). Featuring auto-reset functionality with manual override option, it effectively prevents motor burnout in starter systems, power tools, and HVAC equipment while complying with EU RoHS and REACH environmental directives. With IP67-rated housing and vibration-resistant construction, this SENSATA KLIXON alternative ensures reliable operation in extreme conditions (-40°C to +200°C).

Key Features
  • Dual Protection

    Thermal-Current Hybrid Sensor: Simultaneously monitors winding temperature and current flow
    Fast Trip Response: 4-10s cut-off prevents insulation degradation
    Precision Calibration: ±2% current tolerance meets automotive-grade requirements

  • Robust Performance

    Wide Voltage Coverage: 12VDC to 250VAC systems compatibility
    High Cycle Life: 30,000+ operations (tested per UL 60730-1)

  • Application Flexibility

    Multi-Industry Solution: Optimized for EV charging systems, industrial pumps, AGV robots, and renewable energy equipment
    Custom Configuration: Selectable trip curves (10A/1H/3.5A) and terminal types (fast-on/ring/PCB mount)

  • Safety Compliance

    Certified Protection: Short-circuit withstand (10kA) and arc flash containment
    Lead-Free Construction: Meets RoHS standards
