Switch Gear CAM Switch

And this didn't get picked up at Factory Acceptance Testing?

Then it's an "extra" from the switch gear supplier. Pick up the phone and talk to them.

You can use relay 74 (ANSI Device number) in series with tripping coil and closing coil respectively. However, this relay contact is close or open instantaneously when repectively coil energize.

I haven't studied this very closely, but you might want to ask about a "one-shot" relay configuration. When the coil is energized, this type of relay switches its contacts briefly and then returns to normal. These are typically "ice-cube" relays with 8- or 11-pin sockets, or 14-blade sockets if more contact poles are needed.

thank you sir for your reply .. can you please specify me any relay.

thanks

1. Can you post the exact make * part number

2. what is contacts profile main & aux contacts, NO, NC, CO and MBB [make before break] BBM [break beore make]

thank you borther for your reply .... but i think you didnt get my problem .

the problem is ...i have installed a MV switch gear and that switch gear should give a pulse of 5 sec to PLC whenever the Circuit Breaker goes ON from OFF or from OFF to ON ....so now i have 2 auxiliary contact point from C.B. one is NO and the other is NC...so i m looking for a contact relay , timer or single shot realy or any programeable relay ... who can give me a pulse of 5 sec and then goes off.....and my control voltage is 110V DC and yeah i cannot put a burden on PLC ( means i cannot put any relay on PLC side only contacts.) i hope u got the required information .

Regards Brother.

I got your problem now and was also some of your problem.

Thanks for your reply in detail. I hope that you can use one or both Aux Switches to operate a Single-Shot pulser. Very simple circuits exist or can be made out of discrete components.

Have a fine day & Happy New Year day [It is never too late !!!]

thanks brother... i hve made one or 2 circuits ...with late break and relay make switches ...but preferably i want a ciricuit with a timer ...so if you canhelp me in this one tofind me a timer who can give me a pulse of 5 sec....operating voltage is 110V DC and current is about 10 amp ... i will b v grateful to you ...

kind regards

and happy new year to you as well ... Mayy ALLAH bless you..ameen!

Brother.

Are you clear about time of the pulse?

I wonder it is in your old switchgear by a cam-switch [which is part of the main-switch]

Is your switchgear a Motor-driven Circuit breaker.

If so those have a lot of Add-ons.

Can you give me the exact manufacturer of the old & new one with their part numbers so I could do something which may be of your help.

I think pulsewidth of 5 seconds is too long, but can be achieved by a time-delay-relay [TDR] if it is difficult from an electronic circuit.

As for circuits I am out of touch with practical of electronics for some time but hope a vast expansion to alternates to once only possible by electromechanical devicehhs.

You try to search & i will also search.

Have a nice day.

salamz again ...

yes you are very right ..its was cam switch with circuit breaker and yes circuit break is motor controlled ....

sorry but i dnt have a information about parts ..its just my new switch gear is from EATON and previous was from AEG.

waiting for your response .

kind reagrds

Wa Salaam [On you also Peace from God Almighty].

I hope that the old one still be in your access & you know the functions of the OLD one.

By the way if you look on the old

1. some information may be readable

2. Add-ons like Under-Voltage, or Over-Voltage or No-Voltage cutouts & like that.

Without any further info I am limmited & can't help much.

Have a fine day !!!!!
