Selection Guide/Purchase Recommendations

When selecting a model,focus on the motor insulation class and rated temperature.The ABB 1KHL178012R0016A TRM01’s 180°C upper limit is suitable for Class B/F insulation motors.For Class H insulation motors,a higher temperature rating model is required.The PTC thermistor must be matched with the temperature sensing element embedded in the motor windings.

The installation environment must meet IP20 protection requirements,and the control cabinet must be kept clean and dry.When wiring,confirm the power supply voltage range.While self-powered designs are convenient,voltage stability must be considered.In environments with high vibration,anti-loosening measures should be taken.

Frequently Asked Questions(FAQ)

How to connect the TRM01 to a PTC sensor?The ABB 1KHL178012R0016A TRM01 uses a two-wire connection to a PTC thermistor.The resistance value is<1500Ωat normal temperature and>4000Ωat trip temperature.Shielded cable should be used for wiring,with a length not exceeding 100 meters.

How to reset the module after tripping?

The ABB 1KHL178012R0016A TRM01 supports both automatic and manual reset modes.Automatic reset resumes automatically after the temperature decreases;manual reset requires an external signal or power failure to restart.

Can multiple motors share one TRM01?

It is not recommended.The ABB 1KHL178012R0016A TRM01 is designed for single-motor protection;sharing it with multiple motors will reduce the protection effectiveness.Each important motor should have an independent protection module.

Customer Case Sharing/Successful Application Analysis

A raw material conveying system renovation project at a chemical plant was impressive.The original thermal relay protection was inaccurate,causing frequent malfunctions of the large conveyor motor.We recommended replacing it with the ABB 1KHL178012R0016A TRM01 temperature protection system.

The upgrade yielded significant results,reducing the malfunction rate to zero and greatly improving equipment operational stability.The customer was most satisfied with the 1KHL178012R0016A TRM01’s early warning function,which detected abnormal temperatures before a bearing wear failure occurred,allowing for timely maintenance and preventing major production downtime.The return on investment period was only 6 months,and the customer was extremely satisfied with the protection performance.
