    Be careful that the module gets replaced with the right sort there are the SPD T1 and T2- from memory the two windows one has a gas tube between the N and E, not a MOV, and is preferred for TT installations. To trip both is impressive, or two independent events some time apart.
    They are marketed as if you can change the plug-in module, leaving the wiring intact, in practice finding anywhere selling just the bare modules seems to be rare.

    All the ones I've fitted recently seem to have some kind of keying - often an odd shaped peg that fits into a similarly odd shaped hole in the carrier. They do look a little flimsy though.
