What is the difference between a contactor and a relay?

A contactor is built for switching power circuits repeatedly at high current, often with motor duty ratings (AC-3) and arc-suppressing chambers. A relay switches control signals at low current. In practice: contactor for the motor, relay in the control circuit that drives the contactor coil.

How do I calculate the correct contactor size for a motor?

Use the motor's full-load current, apply the AC-3 rating for the operating voltage, and allow for the number of starts per hour. As a rule of thumb, the contactor's AC-3 rating should be at least equal to the motor FLC, then step up one frame if the duty is heavy.

Do you supply the coil voltage I need?

Coil voltages are specified per order. Send the model number, coil voltage and frequency you require and we will confirm availability and lead time.

Are auxiliary contacts included?

Base models come with the standard auxiliary contact configuration for that frame. Add-on auxiliary blocks and mechanical interlocks can be quoted with the contactor.

use and servicing
7．1The controller must reliably install on the wall or the bracket.
7．2When wiring must according to the controller electrical schematic
diagram wiring, all wires draw out by the base lower extremity two
wiring holes。
7．3In front of the circular telegram, must inspect the controller, the
electric motor, the resistor, the protection screen, the limit switch
and the brake magnet connection is whether correct, must inspect
earths whether reliably, then carries on the idling revolution. If the
controller changes to time the first grade of position, the electric
motor has not started to rotate, after then should stop supplying
power verifies the reason, only then continues to start. After the
electric motor from starts to revolve speed control to, the controller
only then changes to the next position, when transits from a position
to another position, the surge current should not surpass the relay
installation working current. Like wants to stop the electric motor,
should return the controller to the reference (nulling operation).
7．4The controller should the periodic inspection, each week not be
supposed to be short in, and must observe the following request.
7．4．1Should maintain in the friction spot has a thin layer the lubricant
(to be possible to use industry vaseline oil).
7．4．2The contact active face should not have the big melt spot, burns the
melt the spot to be possible to use the superfine file careful repair,
but does not allow the use sandpaper to repair and maintain.
7．4．3The contact active face should not have the big melt spot, burns the
melt the spot to be possible to use the superfine file careful repair,
but does not allow the use sandpaper to repair and maintain.
7．4．4Eliminates in the controller the dust and the soil, may use the
compressed air or do the cloth to wipe.
7．4．5Has damaged the components should promptly replace.
