HC02 Series Motor Thermal Protector Thermal Cutout Switch Replacement for Otter DC 12V-30V for Automotive Motors

The HC02 Series Bimetallic Motor Overload Protector is a precision-engineered thermal protection device designed to safeguard DC motors

from overheating and current overloads in demanding automotive and industrial applications. Combining dual-sensitive bimetallic technology,

it responds to both temperature rise and excessive current, ensuring reliable protection for motors in critical systems such as automotive window regulators,

sunroof mechanisms, wiper motors, and HVAC actuators. Its compact, RoHS-compliant design meets strict automotive and industrial standards (IEC/UL),

making it ideal for OEMs seeking high-performance overload protection in space-constrained environments.

Product feature:

• Dual-Sensitive Protection
  - Bimetallic Technology: Simultaneously monitors temperature and current, triggering instant circuit disconnection at preset thresholds (4-10s response time).
  - Wide Range: Adjustable trip current (1-30A) and temperature (60°C-180°C ±8°C) for precise motor protection.
• Automotive-Grade Reliability
  - Engineered for DC 12V-30V automotive systems, including windshield wipers, power windows, sliding doors, and sunroof motors.
• Global Compliance & Safety
  - RoHS certified.
• Customizable Solutions
  - Optional terminal types and trip curve configurations for HVAC compressors, industrial pumps, and small appliances.
