English Electric's OBX3 Circuit Breaker

AI Thread Summary
The discussion centers on the search for spare parts for the English Electric OBX3 Circuit Breaker, specifically used in heavy industries like steel coil manufacturing since the late 1960s. The original poster is seeking information on where to find these parts or an equivalent circuit breaker that meets the specifications. They are open to purchasing both new and second-hand components, provided they are functional. A link to a potential resource for retrofitting English Electric air breakers is also shared. The thread highlights the need for reliable sources for older industrial equipment.

Hi there..

I'm righting this thread hoping that anybody can help regarding a specific issue.

I'm looking for English electric circuit breakers (OBX3) that whore installed in the late 60's in circuits for heavy Industries, more specifically for the steel coil industries.

I would like to know if anyone knows where I can find any spare parts regarding this specific equipment or if anybody can help me on finding an equivalent circuit breaker for the matter.

I'm willing to buy numerous parts regardless of being new or in second hand, I only need the guarantee that it is working within its specifications.

Please see the pictures below of the English Electric OBX3 Circuit Breaker and its specifications!

Cheers

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
