Language
HCET provides reliable comprehensive solutions for overheating and overcurrent protection.
HCET Key Benefits:
The first China-made round shape thermal protector got UL, TUV and CQC certifications and broke 30 years’ monopoly of German protectors.
Thermal protection HCET-A-S01 is in a well-sealed design，which can prevent product failure from the vacuum impregnation process.
Thermal protection switch is Small in size and suitable to be embedded inside the coil of electric motors.
motor thermal overload switch with a metal casecan bear up to 50KG coil shaping pressure, which has high thermal conductivity and temperature sensitivity.
Pure temperature action type products, bimetal-disc without current and heat effect, accurate temperature control.
HCET Temperature limiters are fitted as safety devices into electric motors, heaters and transformers for popular brands of domestic appliances.
They are often known as temperature controllers, temperature monitors or safety temperature limiters.

Series 01 switch gear is fixed in a positive lock and automatically aligned between the floor of the conductive housing (1) and the contact cap made of steel (2) and insulated from it, plus an integrated fixed silver contact (6), which closes the housing like a button battery. At the same time, the spring snap plate (3) constituting the current transmission element bears the movable contact (4), and discharges current and self heating from the bimetallic plate (5) by applying a continuous and stable contact pressure. The bimetal disc (5) is fixed on a movable contact (4) through which the contact extends without welding or fixing. Therefore, it can work continuously (exposure) and react only to the ambient temperature in the equipment to be protected. When the rated switching temperature is reached, the bimetallic sheet (5) is clamped in its reverse position and the spring clamp sheet (3) is pushed downward.
The contact is suddenly disconnected, and the temperature rise of the protected equipment is interrupted. If the ambient temperature now drops, when the specified reset temperature is reached, the bimetallic strip (5) will bounce back to its original position and the contact will close again
Haichuan temperature control has its own professional R & D team, which has successively obtained dozens of "invention patents" and "utility model patents", and can carry out directional design and development according to the needs of users' products
The original imported core components adopt American EMS chips. Haichuan temperature control products have passed the international authoritative certification such as UI, TUV, CQC, ISO / TS16949, CTI and SGS to achieve precision protection.
Haichuan temperature control products have complete specifications, and can choose many existing models such as "automatic reset", "power-off reset", "temperature and current double protection", which can effectively reduce the development cost and time for you.
Haichuan temperature control self built factory, introduced full-automatic production line and full-automatic chip forming machine, realized full-automatic assembly, more efficient production capacity, greatly shortened production cycle, and ensured faster delivery
