S01 series thermal cutoff switch for reactor
In order to prevent the reactor from overheating and overcurrent when working, thermal protectors are usually installed in it.S01 thermal protector is a small size thermal snap disc switch,it is often used in reactors.It can continually work and only reacts to the ambient temperature in the device to be protected.The principle of snap action of the bimetallic disc under the action of temperature is used to achieve the purpose of protecting the circuit.
Features
Small size and easy for mounting.
Small current effect,no large temperature difference due to over current.
Precise temperature control.
Good sealed, can prevent product failure from vacuum impregnation process.
Longer service life.

FAQ
Q:Are you a product supplier or a factory?
A:Yes, we are a factory. Located in Nanjing, Jiangsu Province. We've been making them for 12 years.
Q:How can I get a free sample?
A:We can provide 5-10 pcs samples for free, but the overseas shipping cost will in your side.
Q:What is the shipping term of bimetal thermal protector?
A:The bimetallic thermal switches we produce are all small size, so the mode of transportation should be subject to the order quantity. For a single order of more than 50,000 pieces, sea transport is the most economical option.If the order quantity of thermal switches is less than 10000 pieces each time, express delivery is the best way, because the weight of 10000 pieces will be less than 50Kg, which is the minimum order quantity of air freight. If the quantity is between 10,000 and 50,000 PCS,express or air transport can be chosen freely according to the weight of different thermal switches.
Q:What parameters should I provide when I want to buy a thermal protector?
A:If you want to buy a thermal protector, please prepare these parameters:
1. Rated voltage, rated current.
2. Operating temperature and rest temperature of thermal protectors.
3. Length of lead wire, color, type and temperature resistance.
4. Application of thermal protector.
5. Mounting requirements if needed, including dimensional requirements.
