The temperature of a 200A relay on s split charge system would depend on the type/ capacity of battery, how low the voltage has reached, the ampage of your alternator..... also is it a 200A peak relay?

My IBS relay has never failed and never gets hot Thumbs Up

Suppose I asked for those sort of replies! Laughing

Basically too many variables too answer question Laughing

Have you actually measured the temp of your IBS relay Glyn? Razz

Yes IBS system is good, IMO better then the Gensis one. (We have both on different 110's. come to think of it the Gensis one uses the can solenoid)

Have had to supply one spare relay to a motor trader who bought a vehicle with a non functioning IBS split charging system. History of failure not known however.

When I first fitted it I hept an eye on it (don't have a thermometer) but just put my hand on it to see what it is like over long distances and it was normally only warm- mine is in the battery box with no airflow to assist any cooling but I don't think it needs any.

Thanks Glyn.

Ours is mounted upside down in battery box. Suppose battery box wall acts as a giant heat sink. Upside down easier to get to terminals.

How hot would say a 200 amp relay get in a typical 12V split charging system?

Is there any real history of relays failing in this type of system?
Brendan


If an electrical device such as a relay is getting hot (as in prelonged touch would hurt the finger) its a sign that something is wrong, i.e wrong size slected or drawing too much current due to a fault.

The contacts will burn up, causing a high resistance to the point that the device would either melt or not work.

A 200A relay should be warm / tepid but not hot, the coil will generate some heat, but not much.
