Magnetic Contactor SC Series AC Contactor TK Series Thermal
Overload Relay
peculiarity
Standard products (GB, IEC, EN, UL) in line with national
specifications and have obtained certified overseas specifications
Electrical life (AC-3) : 1.5 million cycles (Type E02-E3)
Double contact of auxiliary contacts for improved contact
reliability (type E02-N12)
According to the requirements of different wiring, two modes of
direct wiring corresponding type and 0 terminal corresponding type
are provided (SC-E02-SC-E7).
High reliability operation with IC supermagnet (AC input,DC
excitation mode) (E5-N16)
It will not cause coil burning and operation confusion due to
voltage fluctuations, prevent joint melting and damage
When the power supply passes through the regular rated voltage, the
main connector can be used normally even if the voltage drops to
65% of the rated voltage
Prevent the motor from starting under voltage
The power consumption and working VA of the working coil are
greatly reduced
The coil has a wide rated range and is AC/DC common coil
Built-in surge absorption function
A variety of optional units are available
Auxiliary contact unit (front mounted, side mounted)
Coil surge absorption unit
Main circuit surge absorption unit
Independently set the thermal overload relay unit

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
