Each phase such as L1 = 18A, L2 = 20A, L3 = 18A is resistant to 25'Amps.
You can view it by downloading the manual file. Download link
You can get the certificate from the link. For your question, if you want to protect the motor more than its rated value, make high capacity CT + DMP06 series combinations.
You should not use the mini contactors vertically at 90 degrees. This reduces rated currents and reduces product lifetimes.
Thermal overload relay is an equipment that detects abnormal current such as overcurrent to protect the load and must be adjusted in accordance with the actual load current.
Fuses were used to protect against overload or short circuit before MCCBs were manufactured. Fuses serve the same purpose as MCCB, but their protection current and usage areas are limited. MCCBs are used at much higher loads and currents.
|Operating Temperature Range|
between -5 and +70℃
There should be no dew/moisture freezing caused by a sudden temperature change.
|Relative humidity ||45 to 85%RH|
|Installation Environment||Not suitable for environments containing dust, smoke, caustic gas, steam and salt.|
|Storage temperature||-5 to +50℃|
The using conditions of our GMC contactor are as follows: 1. Ambient temperature: -5 ℃ ~ 40 ℃ 2. Humidity: 45 ~ 85%. Altitude: places below 2,000 meters
We are pleased to report that there is an earth fault function in the OCR II (type: LN5) and the 3-pole ACB. It has an NCT (+ and -) terminal. Thus, the user can easily connect Neutral CT to ACB. Please note that the secondary output current of the NCT should be 5A.
Remote start devices that can shut down the equipment need to turn off the MCCB using the motor or solenoid in the remote control. In the ON state, MCCBs will not be allowed to be used by SHT.
TM and ODP are the trigger elements of the overcurrent. It is driven by TM bimetal and ODP wrapped in oil box. TM and ODP are different, that is, ODP needs to correct the rated current because the rated current is different according to the mounting angle.
The breaking current ratings of LSIS MCCBs are between 3A – 1200A. Classified by categories 30AF, 50AF, 100AF, 225AF, 400AF, 600AF, 800AF, 1000AF, 1200AF and classified by Amps/Chassis.
It has IP 54 protection class for D class handles. You can recommend it to your customer.

Below you will find a list of possible combinations for ordering codes and NO and NC arrangements.
Metasol MC contactors have 2 different options for surge protection. Selecting the option with Varistor and varistor + RC Varistor will ensure that the peak voltage is lowered during a surge. Alternatively, the Varistor + RC option also has the ability to reduce the peak voltage, PLUS it will cut off the high frequency wave from the surge voltage. You can see the differences in the image below.
Yes, they are tested according to the NEMA Standard (Addendum to Part 2 of ICS2-2000 Page 5 / Errata). See the reference chart below for NEMA sizes.v
The 4-pole (4P) contactor design is slightly different from the 3-pole ones. Therefore, there is a different auxiliary used. The AU-1 assistant can be ordered for 4P contactors. It is used with the item code below.
The large number of coils used for LS Electric contactors can be a bit confusing when searching. The difference between the “spare” coil and the non-spare leads to this confusion. See the example below. The difference is actually quite simple. The “spare” coil is packaged in a box, while the non-spare coil comes loose. The electrically powered coils are replaceable and both can be ordered.
GMP series EMPRs marked “A” have an automatic reset function. Refer to the model #s list below with auto reset.

LS Electric Miniature Circuit Breaker (MCB) accessories are always mounted on the left. This is because of the mechanical release pin in the MCB. There are various accessories that can be mounted on MCBs. See the combinations below for reference. Up to 4 accessories can be mounted.
No. There are two types of rotary shafts for MCCBs offered by LS Electric. They are of EHU and REH type. The EHU and REH shafts are different and NOT REPLACED.
There are two types of cable/terminal for MCCB auxiliary contacts. See pictures and description below.
LWT: lead wire type
TBT : terminal block type
