Precision-engineered bimetal thermal protectors designed for dual-mode protection against overcurrent (15-60A) and overtemperature (80℃-180℃) in electrical systems.

The HCET HC18/8AM series thermal cutoff switches combine fast-acting bimetal disc technology with CE/UL compliance to prevent equipment burnout across automotive, HVAC, and industrial automation applications.

• Dual-Sensing Protection: Simultaneously monitors temperature rise (T±5℃ calibration) and current overload (up to 60A 250VAC), ideal for capacitor-start motors and split-phase motor protection
• Industrial-Grade Reliability: Tested for 10,000+ cycles, with zinc alloy housing rated for -30℃ to 200℃ operation in harsh environments
• Fast Trip Response: 4-10 second cut-off at setting temperature, significantly faster than standard thermal fuses to prevent motor winding damage
• Global Compliance Ready: Pre-configured for UL/CE/RoHS certification pathways, supporting OEM integration in automotive (IATF 16949 compatible) and industrial equipment
• Customizable Configurations: Optional waterproof terminals, 12-24VDC variants, and silicone-coated leads (UL1007/1015) for EV battery cooling fans or wet location installations
