KSD-308-A high current temperature control is a with double metal sheets for the sense of temperature controller of temperature components, electrical work, double metal sheet in the free state. Contact is closed / disconnected state, when the temperature reaches the action temperature, double metal sheet is heated to produce internal stress and rapid action, open / close contact, cut / connect circuit, thus to temperature control function. When the appliance is cooled to reset temperature, contact automatically closed / open, return to normal working condition.
Electrical parameters: CQC, 45A / 55A / 63A (resistive load)
2, the operating temperature range: 50~150 degrees, temperature accuracy: + 2 + 3 + 5 + 10 C
3, reply and action temperature: 8~100 degrees (Ren Xuan)
4, connection mode: M4, M5
5, the service life is more than 60000 times: automatic reset; manual reset is more than 6000 times
6, the electrical strength: AC 50Hz 1800V for 1min, no flicker, no breakdown
7, contact resistance is less than or equal to 50m.
8, insulation resistance: less than 100M.
9, contact form: normally closed: the temperature rise, the contacts are broken, the temperature drop of contact;
Open type: increasing temperature, contact, temperature drop off contact
10, shell protection grade: IP00
11, grounding mode: connected grounded metal parts by metal shell and thermostat device.
12, installation: fixed
The structure and application:
KSD-308-A series product a with double metal sheets for the sense of temperature controller of temperature components, electrical work, double metal sheet in the free state. Contact is closed / disconnected state, when the temperature reaches the action temperature, bimetallic strip is heated to generate stress and acts quickly, open / close contact, cut / connect circuit, thus to temperature control function. When the appliance is cooled to reset temperature, contact automatically closed / open, return to normal working condition.
Widely used in electric water heater, buckets, Sandwich Toaster, dish washer, dryer, disinfection cabinet, microwave oven, electric coffee pot, electric cooker, refrigerator, air conditioner, glue machine, office equipment, auto seat heater, electric heating appliance.
characteristic
With stable performance, high precision, small volume, light weight, high reliability, long service life, small dry worry on the radio.
Note:
1, the use of touch temperature type installation, should make the metal cover tightly controlled equipment to the installation surface, to ensure that the sense of temperature effect, should be in the sense of temperature is coated with thermal grease or other performance similar to that of the heat conducting medium.
2, the installation can not be loose or cover top collapse, deformation, so as not to affect the performance of.
3, can not let the liquid into the internal thermostat, and shall not make shell cracks, not free to change the shape of the external terminals.
4, at not more than 45A current circuit used in should be copper core section 6 mm 2 wire connection; not more than 55A current circuit using, copper core section 8 mm 2 wire connection. The use of the circuit is not greater than 63A current, should choose the core section of 8 mm copper wires 2.
5, the product should be stored in less than 90% relative humidity, ambient temperature below 40 DEG C warehouse ventilation, clean, dry, non corrosive gas.
