What is the minimum distance to be kept between two numerical relays (7SA86 & 7SA82) in a protection cabinet?

Lakshmanan Paulraj

What is the minimum distance to be kept between two numerical relays (7SA86 & 7SA82) in a protection cabinet (600mm size)? Does it can be fixed next to each other? Please refer me relevant standards for this.

    These are I think part of the Siprotec 5 range from Siemens If so then the regulatory requirement is to follow the maker's instructions  - in turn that does not specify a spacing, at least as far as I can see, but does specify bend radii on the various cables going in. In practice, the room needed to get to the terminals will be the most significant part of the layout  planning.

    Thank you, it's much appreciated, Mr.Mike.

    IEC 60204-1 and IEC 61439-1/2 have to be considered for this.
