Trying to locate a suitable RCBO for a Siemens board with (mostly) 5SX21 breakers in.
![[ElectriciansForums.net] Siemens 5SX range RCBO or best match?](https://www.electriciansforums.net/attachments/2020-10-12-19-06-01-jpg.61364/ "[ElectriciansForums.net] Siemens 5SX range RCBO or best match?")
They don't seem to make this range any more, though I don't think it can be that old. It rather resembles the older MK breakers and I believe Siemens provided some of the electronics for MK stuff.
Busbar is a fork type, though not at the front like Wylex. The other random brands people have added over the years are not perfect fits, though do seem to be good tight connections.
They may not ever have produced an RCBO for this range of course - not sure when it was discontinued.
Since Type testing appears to be out of the window anyway, anyone with experience on good fits?
Been pushing for a new board but landlord is apparently unwilling according to the bathroom fitters I have to communicate through - would be useful to know my options before I put my foot down...
