Electrical Unit identificatio

Hi everyone.

Can anyone help me and tell me what this unit is please. Some one has asked me and I have no idea.



Thank you.

tony's your man here. i'd guess it's a star delta starter.

Looks like an adjustable trip motor protection circuit breaker, with two contactors.
As Tel says, a Star Delta motor starter.

 

[sparky1966]

Do you know how much it would cost to replace it?

Sorry no, I suggest you checkout Allen Bradley or AB Rockwell.

sparky,
Why replace the whole thing?
Which bit is faulty.
On the left you have a motor protection circuit breaker/isolator.
On the right you seem to have 3 contactors.
Are K2M & K3M mechanically interlocked?
Does K3M have a star link in the top we can't see?
At the bottom of K1M you have K4T which suggests a timer.
So I would go with a Y/D starter, open frame.
What is the fault?
I normally build these from parts, I am CAd'ing up a Y/D with ELV control, DC Injection brake, external control buttons & a DOL Aux motor control at the moment, taking a break from that to come on here.
My own 1st principles design, build & install.

i've got 50p on the windings being down for the motor

 

[Deleted member 26818]

What, a whole 50p?

 

[dcelectrical]

well i would go to a pound but i don't want to seem over enthusiastic specially given the condition of the control gear in the picture, i've put worse gear back into service in the dark days at marks and spencer

Telemecanique star delta starter with a motor protection MCCB mounted to the left.

What is the fault? That little lot will cost a small fortune to replace en-mass.

Tony,
Get yourself a new pair of glasses will ya!
Its AB kit not Tele

 

[wattsup]

Is it not a mains reversing contactor?

Suppose it having AB printed on it gives the game away.

My eyesight isn’t very good now a days. I have a 19” monitor and the highest resolution I can have it on is 800X600 any higher and I can’t see to read even with my reading glasses on.
