Time current curves data for P&B Golds Relays

[ycliff]

I'm looking for the time current curves for various P&B Golds THERMAL O/L & STALLING RELAYS. Any help in finding this information would be greatly appreciated!

I've tried their website (

http://www.pbeng.co.uk/)

and even contacting them but with no luck.

I can't find any reference on the manufacturer's website to 'Golds' relays. What did they say when you contacted them?

 

[ycliff]

they never replied...! see url relating to golds series:

Might be a good reason to recommend another relay manufacturer.

 

[ycliff]

yes, but unfortunately i'm not designing a sys. w/ these relays (they're obsolete)...i'm modeling a power system in software that has these relays (using etap). etap does not have the model for the relays in there and i am unable to find the data (tcc curves) for the relays.

All you can do is state that the relays are obsolete and the manufacturer can't supply curves, and recommend a different replacement relay.

my first contribution on eng tips. I incidentally was doing an inspection on a customer forwarding a claim for burnt out 75 HP motor and the time current current is stuck right at the front of the relay but the units are damn old. There is a starting and running curve at your disposal.
