Current vs Time Curve

Application Note:

1.

Be sure to use washer to prevent screws from loosening, all the terminals or

copper bar must be in direct contact with the contactor’s terminals. Screw

tightening torque is specified below. Exceeding the maximum torque can lead

to product failure.

•

Contact torque: 30 - 40 lb.in (3.4 - 4.5 N.m) Max. Active length of thread

is 7.0 mm

•

Mounting torque: 20 lb.in (2.3 N.m)

2. Contact terminals are polarized so refer to drawing during connecting. We

suggest using a varistor rather than diode as a surge protector.

3. Do not use if dropped.

4. Avoid installing in a strong magnetic field (close to a transformer or magnet),

or near a heat source.

5. Electrical life

Use per load capability and life cycle limits so as not to cause a function

failure (treat the contactor as a product with specified life and replace it when

necessary). It is possible to make parts burn around the contactor once

operating failure occurs. It is necessary to take layout into account and to

make sure power shall be cut off within 1 second.

6. Lifetime of internal gas diffusion

The contactor is sealed and filled with gas, lifetime of gas diffusion is

determined by temperature in contact chamber (ambient temperature +

temperature generated by contact operation). Operate only in an ambient

temperature from -40 to +85 ˚C.

7.

Drive power must be greater than coil power or it will reduce performance

capability.

8. Avoid debris or oil contamination on the main terminals to optimize contact

and avoid excess heat generation.
