A couple points.
1) Be sure to only buy name brand on that style breaker. (Blue Sea is a good brand)
None at all - if you can find a "UL" listing on that breaker, and if 200A OCP is suitable substitute for 30A OCP, and if voltage and AIC rating are high enough.
UL is Underwriters Laboratories.Sorry, I'm new to the forum and haven't picked up the lingo yet.
I understood the "None at all" bit.
I didn't understand anything after that.
Thanks anyway.
Blue Sea only seem to go up to 150 amps with surface mounts and their website is painful to navigate on a phone.
Are there any other reliable manufacturers that make a 200 amp version?
Cheers
Here's a 200a rated version-
187-Series Circuit Breaker - Surface Mount 200A - Blue Sea Systems
Thermal circuit breakers provide heavy duty circuit protection for 25 to 200 Amp loads when switching and circuit protection are both required.www.bluesea.com
Maximum Voltage | 48V DC |
Interrupt Capacity
| 5000A @ 14VDC 3000A @ 28VDC 1500A @ 48VDC |
Thank you very much for taking the time to do that.12V system, you can get away with a lot more. But I do think LiFePO4 batteries could deliver high short circuit current if BMS failed.
So I'd prefer an expensive breaker, or a fuse. Be sure to use appropriate fuse holder. In particular for MRBF which looks like it could bolt directly to battery, but I think that would bypass/short the fuse.
ANL Fuse - 200 Amp - Blue Sea Systems
Use with ANL Fuse Blocks for many applications with 35-750 Amp loadswww.bluesea.com
MRBF Terminal Fuse - 200A - Blue Sea Systems
Space-saving ignition protected fuse for 30 to 300 Amp loads. Must use with Terminal Fuse Block.www.bluesea.com
Fuse A3T / Class T 200 Amp - Blue Sea Systems
Use with Class T Fuse Blocks for circuit protection of devices including inverters. high interrupt capacity for large battery banks including Lithium-ion and TPPL batteries.www.bluesea.com
