make and break rating of aux. relay contact
make and break rating of aux. relay contact
(OP)
Hi all,
MOst of the aux. relay manufacturer doesn't mentioned make and break capacity of aux. relay contact.
They mention 125VDC, 10A
Is this 10A is make capacity or break capacity or continuous current carrying capacity.
I am looking for a relay with 125VDC, 3A make capacity.
Help for anyone is highly appreciated.

And in most applications the rating is 10,000 operations, where you can increase the contact rating if you are willing to live with fewer operations to failure.

Try the ABB MG6 relay.
Make and Carry:
30 Amps @ 575 Volts ac for one minute,12 Amps continuous
Break:
Non-inductive loads only:
30 Amps @ 115 Volts ac
20 Amps @ 230 Volts ac
15 Amps @ 460 Volts ac
10 Amps @ 575 Volts ac
30 Amps @ 12 Volts dc
15 Amps @ 24 Volts dc
10 Amps @ 32 Volts dc
8 Amps @ 48 Volts dc
3 Amps @ 125 Volts dc ***
1 Amps @ 250 Volts dc

Make/break capacity CLOSE 1000 W/VA
BREAK 30 VA
40 W resistive
25 W/VA at L/R ≤ 50 ms

HI DPC,
Little bit confusion.
"making capacity by putting multiple contacts in parallel."
"Breaking capacity can be increased by putting multiple contacts in series"
Why for breaking capacity, contacts should be in seris.
As per my understanding,while breaking also you are breaking current and need contacts in parallel.
your explanation is highly appreciated.
