T echnical Specification Of 02 Thermal Protector
1 Usage
02 thermal protector possess the benefits of miniature size 、 shell insulation 、 sensitive in action 、 long life
etc.Widely used in electric power points 、 electrical appliances 、 fluorescent ballasts 、 transformers 、 automobile
motor 、 integrated circuit and general electric equipment of dual hot flow protection function.
2 Appearance and structure ：
Note: 200 ° c, heat-resistant material shell combustion level V
3 P roperty
3.1 V oted current
4A/DC12V 、 3A/DC24V 、 3A/AC115V 、 2A/AC250V .
3.2 Disconnect temperature: 30 ~ 155 ° c , reset temperature 20~ 110 ° c (see “ opening and reset temperature
drawing ” ).
3.3 Ant -tension test : P roduct test pins should with no fault, sliding out when bear ing ＞＝ 20N .
3.4 Insulation voltage :
a. Products in the lead when disconnect between AC660V shall withstand, 1min without breakdown
flashover phenomenon ;
b. Product leads and insulated shell, between AC1 5 00V can withstand 2 S without breakdown flashover
phenomenon .(striking current is 0.5mA)
3.5 Insulation resistance: under normal conditions, fuses and insulation shell insulation resistance in 100M Ω
above. (used forDC500V meter)
3. 6 Contact resistance: P roduct contact resistance shall not be more than 50m Ω 。
3.7 High temperature resistant test: The a ction temperature should keep in 96h in temperature of 50 ° c rated
movements in air environment .
3.8 Low temperature resistance test: product should keep in 96h when in air environment - 40 ° c
3.9 Ant-vibration test: thermal protectors shall withstand amplitude, frequency changing 1.5 mm 10 ~ 55Hz,
scanning change cycle 3-5 times/min, vibration direction X,Y,Z, in each direction, each successive 2h vibration.
3.10 Drop test: products high free fall from 0.7 m.
3.11 Compression test: products shall stand 1min in 100N static pressure.
3.7,3.8,3.9,3.10,3.11 should meet the following requirements :
