B) International standard: IEC 61095
7) Operation times: >30, 000 times
8) Protection class: IP 20
9) Direct running, reverse installment, seal type structure, distinct running indication
10) DIN rail installment, modulus outline, avoiding maintenance

B) LC1-F series AC contactor is applicable to the circuits up to the rated voltage 1000V AC 50Hz or 60Hz, rated current up to 780A, for long distance breaking circuit and frequently starting or control the motor. It also can be used for the control of distribution circuits of rated current form 200A to 1600A.

C) LA1, LA2-D series Auxiliary Contact Block
1) LA1-D series auxiliary contact blocks are installed on the top of LA2-D control relay or LC1-D contactor for expanding the couples of auxiliary contacts points.
2.)Owing to adopting the contacting functions of sliding frictions, the contactor block can be self-cleaning & ensure the electric circuit to be reliable.
3)LA2-D timer delay auxiliary contact blocks are combined with LC1-D AC contactor & LA1-D auxiliary contact block into LC3-D star-delta reduced voltage starter is to start motor.

D)3TF series AC contactors are suitable in electrical system with AC 50/60Hz, rated operational voltage up to 660V. In AC-3 usage, rated operational voltage up to 380V, rated operational current up to 630A to make or break remote motors or system. They can form electromagnetic starters with suitable thermal overload relays 3UA series to protect system and motors against overload or phase-failure. They are made according to IEC947-2, BS5424 & VDE0660.
The contactor is a straight motion mechanism having double-breaking contacts. The auxiliary contacts are arranged 2 NO, 2NC at most. It is employed the flexible lockig connection between the contact support and core, There are no arc-isoladted panel in the le≤22A contactors. In the ln≥32A contactors, there are moulded arc-chute with arc-isolated panel. Because all contacts are made of high non-fusibility and against corrosion silver alloy. All series products can be mounted by screws, le≤32A contactor also by installation rail.

E)S-K series magnetic AC contactors are a new generation of contactors. The contactor is suitable for making and breaking remote circuits or frequent starting and controlling of AC motor with 50/60Hz rated voltage up to 660V, rated operating current 9,12,16,22,30,40,50 and 105A at rated operating voltage 380V under the utilization category AC-3.

F)SC AC contactor is suitable for using in the circuits voltage up to 660V 50Hz or 60Hz, rated current up to 150A, for making & breaking, and for frequent starting & controlling the motor.
The product has the features of small volume, light weight, low power consumption, high efficiency, safe reliable etc. It also can be combined with contact head group, air time delay block, relay, thermal relay accessories, into motor starter etc, multiseries products. It conforms with IEC158 & IEC337.

G)S-N series AC contactors are suitable for AC 50Hz or 60Hz, rated voltage up to 660V, mainly used as putting through long distance, breaking circuit and frequently starting or controlling AC motor. It can also be used for counter-connection breaking of squirrel-cage motor in the case of reducing working current.
