Langfeng T44 series contactless contactor instructions
● product overview:
T44 series
contactless contactor（solid-state contactors） is modern microelectronics technology and power electronic
technology is developed combining A new type of contactless switch device, the
utility model in 2009 was issued by the State Intellectual Property Office The
certificate (Patent No.: ZL200920224997.3 products registered trademark: 
).
A new generation of contactless contactor adopts photoelectric isolation type alternating current zero crossing triggering technique, the main parts of the device are imported, and strict production process, to ensure the high reliability, the main characteristics of products are: shock, moisture resistance and corrosion resistance, anti explosion, fast switching speed, no noise, long service life, no electric spark switch. Can be widely used in building ceramics production lines, chemical production, machine processing, light control, electric heating control, coal chemical industry, the environment, the use of switching frequent occasions, is a new generation of optimal update the traditional electromagnetic contactor.

● Langfeng T44 series contactless contactor type spectrum:
● installation and size chart:
From T44A10-3P to T44A40-3P (including the corresponding T44N10-3P to T44N40-3P), Are the same size.
● Lang wind T44 series contactless contactor use matters needing attention:
1 ：A1 B1 C1 380V A2 B2 C2 three-phase power input is connected to the load terminal crimping firmly remember to.
2： strictly according to product selection table, according to the load situation specific selection of contactless contactor suitable, not allowed to use overloading.
3：The 3 access control input signal to check carefully, to avoid the wrong input signal, caused by man-made fault.
4 ：strictly control the various ways of using contactless contactor are positive, responsible for all the losses caused by the customer, if the customer need positive inversion of control products, our company can buy a three-phase motor reverse dedicated control module, the concrete can contact our technical staff.
5 ：strictly for the system of star - Delta conversion.
6: When used in heating systems, advance instructions, because the heat sink is set according to the motor load. When used in heating systems, electric current can not exceed the motor nominal current. Otherwise it will overheat.
