Hi I'm wondering if there are safety standards, perhaps such as IEC/UL 60950, that require a safety approvals certification file listing on 48VDC electrical distribution equipment - i.e. fused disconnect switch, with blown fuse indicator (could be a QIFFI fuse or electronic circuit module). Application is a station battery needing a 1200A disconnect means, with 66 kA short-circuit amps capability. I've found that some OEMs offer only products with UL recognition - which is not valid in Canada. Other OEMs (even Canadian ones) claim that approvals are unnecessary because 48V is a safe touch voltage (never mind the energy discharge and arc flash hazards!) signed, "PERPLEXED" Thanks!
