Anderson connecter vs battery disconnect switch

[MT off grid]

I have been trying to find a good quality battery disconnect switch that can handle 60+ volts DC but the ones I am finding look very questionable in quality, I have several bluesea disconnects llaying but unfortunately unknown to me that they are only good to 48 volts,Iif I can't find a good quality disconnect soon I am thinking about going with the 300 amp Anderson connector as my disconnect, does anyone see an issue with going this route or atleast have a source for good quality high volt disconnect switches?

Using an Anderson connector is going to be rather sparky?

I was thinking the same thing but it would mostly just be used as an emergency disconnect, shouldn't be much of a spark as a disconnect

Consider skipping it and just lift a cable from the stud as needed. Mine tend to remain connected continuous for years at a time.

If under load it could be a good one. Also when connecting there might be a spark from the surge of the capacitors charging.
I agree with @time2roll , that it might just be easier to lift the cable from the stud if this is not a regular need to disconnect.

Under a load yes but in an emergency I'm sure I wouldn't mind a spark, would also he nice to have a quick way to work on things and have a way to kill the power

It is clearly a user preference. I have used switches, Anderson connectors and unfastened the lug depending on a particular use case.

A switch would be great if I could find a 60+ amp quality switch

These claim to be anti spark but no clue as to your suitability or power needs.

I could use those on other projects, unfortunately I need 300 amp capacity

Square-D circuit breaker

Anyone familiar with Square-D circuit breakers? I just ordered the following on ebay and now I'm thinking it might not be a shunt-trip but only has an aux switch: https://www.ebay.com/itm/353475617286 P/N is KHL3625025DC2350 (W/ AUX SWITCH SHUNT TRIP) but I cannot find any details in the...

Rated to 125VDC but 300A sounds like expensive

It's a dead link, but I'm sure it's not cheap

A fuse will open if there is an emergency. Otherwise turn stuff off normal and then lift the cable.

Does the battery have a BMS with an app to cut power? OK to use that too.

BMS's have a reset/on off switch but wanting something easier amd faster then waiting for all 3 BMS'S to shut down
