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.

2.1 controllers outer coverings are the protected types.
2.2 controllers contact systems for the double break point, the translation type, the extinguishing of arc system use the semi-enclosed type longitudinal seal pottery clay explosion chamber, and matches by the strong magnetism blows the electric circuit, extinguishing of arc ability.
2.3 contacts systems structure for the building block box type, the two-row arrangement, the assembly is convenient, the structure compact disassembles and assembles easily.
2.4 contacts closed and the separation relies on the bakelite cam piece composition different angle, with revolves the way realization.

build in and servicing

6.1 installments precheck controller, like determination controller operation clever, when the files position is clear, the controller only then may install.
6.2 controllers must reliably fix on angle iron stand 'or' operation. Taiwan, outside meet the electric cable wire to be possible to penetrate by the foundation on hole.
6.3 controllers should reliably earth.
6.4 controllers stators electric circuit contact must install the complete extinguishing of arc cover.
6.5 with skids the friction in controller all rotations place, must the regular apply oil fat, by reduce the friction 6.6 controllers when work the contact but produces as a result of the electric arc burns black or the singeing phenomenon, this does not affect its performance, does not need to eliminate, otherwise counter-
can urge the controller to damage ahead of time.
6.7 controllers contacts exceeds the quota the travelling schedule to be smaller than when 0.5 millimeter should exchange the new contact, when installs the contact system and moves, the static contact
guidance place on its roller axis spreads the lubricating grease, and adjusts the double break point contact closed and the separation synchronism.
6.8 should eliminate in the controller regularly the dust.
6.9 pays attention to the fastening parts frequently whether has the loose situation, like has must eliminate.
