Product Description

HCET-A/TB02 Bimetallic Thermal Protector Replace SEKI ST-22 Snap-Action Switch for Heating Cables & Micro Motors  

The HCET-A/TB02 is a compact, RoHS-compliant bimetallic thermostat engineered for sensitive circuit protection in critical applications. With a patented snap-action mechanism (Patent: ZL2013 20699495.2), it delivers ±3℃ accuracy across 30-155℃ ranges, making it the ideal upgrade for SEKI ST-22 JP series in battery management systems, low-current devices, and thermal cable networks.

Product feature:

Interchangeable Compatibility
Direct replacement for ST-22 JP with enhanced thermal response
Dual Configuration
Normally Open (Model K) & Normally Closed (Model B) options
Military-Grade Reliability
30,000+ mechanical cycles under IEC 60691 standards
Industry-Specific Solutions
Battery Safety: Prevents thermal runaway in Li-ion packs and BMS boards
Smart Heating: Embedded protection for electric blankets, floor heating systems
Transformer Safety: Fail-safe mechanism for telecom/power supply units
