This question has been asked a few time, so this might be a great place to discuss here.
Not a discussionon Fuse verse Circuit BreakerCB but what options are available.
#1 must be compliant with relevant country regulations and guidelines.
#2 need to be DC rated within the voltage range, withnon polarized2 poleforboth POS, NEG terminals
#3 breaking current needs to be high enough to besuitable (> 10kA is advised for typical 10kWh 48vpack)
#4 maximum current amperes of CBto suit discharge and charge rates and equipment
#5 maximum current amperesof CB needs to be appropriate forcabling it is to protect
#6 remote triggering accessory to be a suitable voltage to control logic (typically pack voltage)
#7optional remote sense state to monitor the existing state of CB
#8 suitability for isolation conforming to IEC 60947-2
Every manufacturer has many different options. AC breakerssometimes also have DC ratingswith different characteristics. Alow cost option maybe to utilise an existing 3 phase second hand unitwith just 2 of the poles used. But confirm the product is suitable as AC rating does not mean itis suitable for this application.
Note+100A continuous CB are not small or light.
