1. Bimetal thermostat for transformer heating and motor
2. Snap action thermostat, can be normally closed or open
3. Dia 8mm
TS01-1 Button type bimetal thermostat is snap action thermostat. Bimetal trips off or on quickly to open or close the circuit when temperature reaches the prescribed value. It can replace Microtherm F11 or Thermik S01.
* Special Features of bimetal thermostat TS01 series:
1. Small size and button type
2. Low current sensitivity
3. Precision temperature control
* Electrical Ratings of bimetal thermostat:
1. 250VAC: 3A
2. 125VAC: 6A
3. 24VDC: 6A
4. Contact Resistance:<30mΩ
5. Insulation resistance: 2KV
6. Normally Closed or Normally Open optional
* Temperature ratings and range of TS01 series bimetal thermostat:
1. Action temp: 60~200C,every 5C per rating
2. Tolerance of Action temp: ±5C;
3. Reset temp: 1/3 lower than action temp;
4. Tolerance of reset temp: ±15C
* Applications:
1. Electrical tools, motors, heating elements
2. Transformer, ballast.
3. Coil.
* Type Classification of bimetal thermostat:
1. Type 2B: Automatic Control, micro-disconnection on operation, and, manufacturing deviation and drift of its operating value, operating time or operating sequence have been declared and tested. Since this kind of thermostat is widely used in transformers and other heating appliances, type 2B is the most suitable classification.
* Crucial tests and relevant methods of bimetal thermostat:
1. Electric strength: Test voltage 1250VAC 50HZ applied between insulation sleeve and live parts, and 500VAC applied between two opened contacts, for 1 minute, no flashover or breakdown.
2. Endurance test: Number of automatic cycles declared as 10,000 cycles, the test shall be carried out under 1.15 VR for 200 cycles, the balance 9800 cycles should be carried out under rated voltage
3. Moisture resistance test:
Humidity Treatment:
Relative humidity(%): 91-95%
Temperature: (20-30+/-1) C degree
Keep samples under this environment for 48 hours. No damage so as to impair compliance with this standard.
4. Manufacturing deviation:
The appropriate operating value or operating sequence shall be recorded for each sample. No two samples shall differ from each other by an amount exceeding the declared manufacturing deviation.
Tolerance of trip-off temperature: +/-5K
The temperature of oven may be rapidly increased to 10K below the expected operating temperature. Rate of temperature change reduced to max 0.5K/min or as declared.
5. Synchorous test:
5 minutes continuous operation test, no flicking occurs.
6. Relevant Standard number:
EN60730-1, EN60730-2-9; UL 873
