Connecting Thermal Protection to ABB MS1 16-20 Manual Circuit Breaker for 2.2kW Single-Phase Motor

Hello and help, please.
I have a single-phase ~ 230V / 50Hz motor with 2.2kW 2820 rpm burned, current according to the rating plate: 15.3A. The motor has two 45 micronF capacitors installed.
The start winding and work winding are burnt. After disassembly for rewinding, it turned out that there is also a thermostat connected to the winding but not connected to the control box. I decided to improve this protection at the stage of winding replacement by performing control in the breaker box.
The ABB MS1 16-20 manual circuit breaker is located in this motor breaker box. It looks like the picture below:

How to attach the above thermal protection to this switch? Should the auxiliary contacts HK1-20 be used for this? (picture)

Is this the right accessory for this purpose? I do not want to change the switch because it fits well in the housing and there is still space on the rail for such contacts.
The circuit breaker has these two connection diagrams assigned to a single-phase motor:

Thank you in advance for your interest and kind response.

What temperature is the thermal sensor at? It must be connected to the control circuit of the contactor

Auxiliary contacts are used to control the contactor, signaling circuits, etc., you don't need them / if you don't have a contactor /. The machine switch / on the photo above / is in itself a thermal and overload protection - it must be properly adjusted to the motor and its load.

Hello
Depending on the type of thermal protection - ordinary TK contact or PTC protection (additional transducer needed)?

I am sorry that yesterday I did not immediately respond to the responses to my program, but today I am only in contact with the workshop where my engine is being revamped.
Indeed, on this switch, in the lower left corner below the knob, there is a setting element with such positions 10, 12, 14, 16A.
The value of thermal protection (the one that burned in the old winding) I do not know, because it is completely melted.
I will tell you in an hour what security the workshop has established.
I can't indicate which auxiliary windings. I give below the diagram from the catalog card of this switch.

Thank you for your interest.

I will determine in an hour with the workshop what thermal sensor they have put into the winding.
Which of these pins is the control circuit?

Is there a cam controlling the auxiliary relay on the left side of the switch.

I can't see the cam there. Both sides of this switch are smooth and labeled.

I will determine today what kind of fuse this is.

I am adding a datasheet for this switch.

In the motor, our only thermistor sensor, to use it you would have to use e.g.

Thanks for the advice. Good thermostat. If it would still accumulate subsequent shutdowns in memory, so that you can download logs via USB, I would install it immediately.

The thermal sensor is mounted in the winding at 130oC.

When I watched this burnt sensor it looked like (googled) PTC protection. Such a similar (even several in a row) intends to install a workshop rewinding the engine.
But I understand that this switch can control excessive current in the motor stator and control the temperature of this winding through a sensor in the winding? It is only a matter of setting the current range switch on the front and connecting the sensor with it.

Motor protection is based on the principle.
1. The thermal protection works when the motor current is exceeded, it is set depending on the conditions to 1.1 In or in hazardous rooms to 0.9 In, for example, when the motor is under a greater load as its rated power.
2. The thermal sensor built into the motor windings is designed to turn off the engine when e.g. it has a lot of starts in a short time, or its fins are dirty and the temperature discharge is small. The control circuits plug in auxiliary safety contacts, which will turn off the device or machine in an emergency damage.

Yes

No . An additional device is needed

In point 2. sorry winding temperature sensor.

I understood that I had to add to the existing manual switch a thermostat (TER7) connected to a PTC sensor in the winding. Of course, if there will be room in the housing.
I like this solution.
Thank you very much for advice and commitment. For my part, the topic may be closed. Greetings.

In the motor circuit you can connect a lot of protections against overload, temperature, loss of one phase, under current, etc.

I followed the advice. I set the circuit breaker to the required max. Current load. The temperature sensor is mounted in the winding. I will mount an element in the box cooperating with this sensor and switching off the motor when the winding overheats. Thank you. I close the topic.
