BSI BS 646:1958+A2:2013

This British Standard relates to cartridge fuse-links of current-ratings up to 5 amperes (hitherto known as Type A fuse-links) intended for use in plugs, and socket-outlet adaptors Text deleted for two-wire circuits of which the declared voltage does not exceed 250 volts a.c. at 50 cycles per second, or 250 volts d.c.

Fuse-links for use in plugs specified in BS 1363 are separately provided for in BS 1362.

Non-rewireable fuse-links (formerly Type A) are for use in plugs and socket-outlet adaptors to BS 546 for two-wire a.c. or d.c. circuits up to 250 volts.

They include specifications for current ratings, performance, dimensions, marking, and type tests (including the testing enclosure for duty tests).

The requirements for Type B fuse-links previously included in BS 646:1935 have been superseded by BS 2950:1958.
