Siemens 2353 Cutout

[PeatBog]

Can't see a bs number on it. Does anyone know if it is a BS 1361 fuse?

cutouts are fitted with either a BS1361 or BS88. only way to know for definite is to look, which involves remving fuse, which is illegal. either contact DNO and ask, or put 'not verified' or 'sealed' no cert
