Magnetic Contactors
Answer :
You may select LCD125xx with LRD16. Based on the specification of the motor, the contactor, and thermal overload relay is within the acceptable range. We suggest you to have a certified electrician to check the following to understand the cause of the trip.
1. Test the Thermal Overload Relay (possible hardware is faulty)
2. Test for Phase Unbalance.
3. Possible grounding issues due to leakage.
The most common cause of thermal overload to a trip is grounding issues due to leakage. Hence, if phase unbalances, it might still cause the trip.
Answer :
You may consider LC1D25U7 and LRD21. Do not that the rated operational current is 25A while their old model should be 32A based on the image, but the motor ratings are the same. Kindly refer to the datasheet here for LC1D25U7 and here for LRD21.
Answer :
It will have to depend on your requirements, as the contactor comes with 1N/O + 1N/C.
Answer :
You may consider LC1D18BNE.
Answer :
You may consider LC1D12M7.
Answer :
You may consider SZ-A11. Kindly take note of the Auxiliary Contact, 1NO+1NC.
Answer :
You may consider Schneider LC1D65AEHE. Kindly take note of the operational current only operate until 65A for AC-3.
Answer :
You may consider LC1D18BNE or 8502SCO2V02S. Kindly note that for LC1D18BNE, the TeSys D contactor 3P 18A AC-3 up to 440V coil 24-60V AC/DC, and for 8502SCO2V02S, the type S non-reversing magnetic contactor, NEMA Size 1, 27 A, 3 P, 110/120 VAC 50/60 Hz coil, separate control, open.
