The HC02 Bimetal Overload Protector is a high-precision, dual-sensing device designed to safeguard motors and transformers from overheating, overcurrent, and short circuits. Engineered to replace Otter PB G series protectors, it combines temperature and current sensitivity for superior reliability in automotive, industrial, and HVAC applications.

With customizable trip currents (1-30A) and fast response times (4-10s), the HC02 ensures critical equipment like car window lift motors, wiper systems, and industrial pumps operate safely under extreme conditions. Its compact, RoHS-compliant design meets global standards for durability and environmental safety, making it the ideal choice for OEMs seeking cost-effective, high-performance thermal protection.
