Introduction:
-
- Lorentzzi® CJX2 contactor is a very popular relay switch with a current of from 6 amps to maximum 95 amps, suitable for three-phase loads such as heating elements or motors.
- Additionally, it can be used to control the single phase loads as well.
- Its coil voltage can be selected as either AC 220 V or DC 24 V. AC 220 V coil voltage means that when a control voltage is applied to the control terminal, the three contacts close. DC 24 V coil voltage operates in the same manner.
- The controlled voltage can be maximum AC 690 V.
- Compared to our three-phase solid-state relays, the CJX2 AC contactor can handle higher currents and generates less heat during operation, but it also has disadvantages such as higher noise levels and greater contact wear.
- For more information on the differences between three-phase solid-state relays (SSRs) and AC contactors, read the following article: SSRs vs. AC Contactors: Which is Better for Temperature Control Systems?

How To Choose The Right CJX2 Contactor?
1.Choose the right current
Lorentzzi® brand CJX2 contactor has a load current range of 6 amps to a maximum of 95 amps. For example, if your motor power is 3 kW, the appropriate current should be 3000/380*2=16 amps, therefore the appropriate model is CJX2-18. The calculation formula is: Current = Rated Power / 380(or 3 phase 220 V)*2.
2.Control coil voltage
The second thing is to select the appropriate coil voltage. The control voltage of the Lorentzzi® CJX2 contactor can be AC 110 V, AC 220 V, AC 24 V, AC 380 V, DC 24 V, etc. If you want to use AC 220 V to control the switching of an AC 380 V load, the coil voltage should be AC220V.
3.Selection of auxiliary contacts
Lorentzzi® CJX2 contactor auxiliary contacts can be 1 NO(model CJX2-XX10), 1 NC(model CJX2-XX01), 1 NO+1 NC(model CJX2-XX11), please choose the auxiliary contacts you want before purchasing.
4.Certification consideration
Lorentzzi® CJX2 is CE and CCC certified. If you have a large order and require other certifications, we can process them together.
