Waterproof HCET Overcurrent Trip Switch Circuit Breaker for Air Compressor
The HCET 88/98 series are mechatronic protection devices specifically designed for air compressors and other applications in high humidity environments with strong vibration. Utilizing a bimetal mechanical drive system, these protectors respond to current thermal effects by bending the bimetal strip to directly cut off the circuit, preventing motor overheating damage.
