SUMMARY

The schematic symbol in question represents a disconnect switch without fuse protection, specifically a knife blade switch suitable for various amp ratings such as 20 A, 30 A, 60 A, and 100 A. This symbol is part of a one-line diagram for a solar power supply system with battery backup, which includes two inverters and a load splitter. The drawing incorporates a mix of American and European symbols due to its Canadian origin, but it is essential to recognize the potential for misinterpretation, as misunderstandings can lead to serious safety issues.

PREREQUISITES
  • Understanding of electrical schematic symbols
  • Knowledge of solar power systems and battery backup configurations
  • Familiarity with disconnect switches and their applications
  • Awareness of safety standards in electrical installations
NEXT STEPS
  • Research the specifications and applications of knife blade disconnect switches
  • Learn about the differences between fused and non-fused disconnects
  • Study the standards for electrical symbols used in different regions, including American and European
  • Explore safety protocols for working with solar power systems and battery backups
USEFUL FOR

Electrical engineers, solar power system designers, safety inspectors, and anyone involved in the installation or maintenance of electrical systems in renewable energy applications.

This is part of a one-line diagram of a solar-with-battery backup power supply system. Two inverters, one for the batteries and one for the solar panels, feed these things (one of which I've circled in red) at the inputs to a splitter, which splits the load between the two sources. I think the mystery symbol represents a current or power sensor integral to the splitter, but I'm not sure.

The drawing was made by a Canadian and therefore contains a mix of American and European symbols, but the client was in Tanzania, so it could be African as well. We use the client's country's symbols if we know them.

I think it is a disconnect box - like a switch. Agreed it is not ideal. People actually die from this type of misunderstanding - so please pay attention.
 
It is a Disconnect w/o fuse protection. Basically a knife blade switch with the appropriate Amp rating (not stated, but implied). These types of Disconnects come in the standard ratings: 20 A, 30 A, 60 A, 100 A, ... on up.

A fused Disconnect would have a diagonal line thru it and often a note for the size of fuse (which could be any value up to the rating of the disconnect),

A cross on this symbol would NOT be a disconnect but a combination motor starter.
 
Thanks. I've been able to confirm that it is a disconnect switch.
