Ice Cube Relay ratings

After speaking with an engineer with the manufacture he was able to shed some light on the subject and explain a few things. He directed me to these attached specs.

The .8A @ 250VAC inductive rating is based on 200,000 minimum life operations as listed/tested. Attached is an inductive (and resistive) cure of amperage relation to the life operations.

The curve shows the .8A @ 250VAC to equal (200 X 10 to the third power) or 200 X 1,000 = 200,000.
At my 1.7A inductive current it shows 100 X 1,000 = 100,000. So basically at 1.7A ill limit the listed life operations to half which explains my little to no arc. My expected 6 operations max a day will make the relay last a very long time for me.

There is also a max switching current that is also variable depending on the voltage when dealing with inductive load as 120VAC it is increased to 3A VS the 2A at 250VAC

Better wire a counter to it to make sure you get expected number of operations before any failure.:lol:
 
Double up on the contacts??

Double up on the contacts??

If it is a simple ice cube relay with 3 sets of contacts, then triple up on the contacts by jumpering the contacts...

new guy... oh durn the relay contact are burned . it will take a week to get a new one..

old guy .. change the wires on the contact base to the other set of contacts ... keep the line running.

new guy..... UGH????:slaphead:

When I am building it, if I use a 3 or 4 pole relay, it is because I needed all three or four poles.

I do use two pole relays quite often though where only one pole is utilized, but that is usually because a single pole isn't really that significantly lower in cost, plus it gets frustrating when on a service call and you need a two pole and all you have is single pole with you for whatever reason.

Helped an old widow with some burnt up contacts on a pressure switch get her well running one night in a similar way.
