IEC 60269-2 can anyone help....

[Baddegg]

Recently installed a switched fuse connection unit and the 63a fuse is an IEC 60269-2 63a fuse, on the certification I need a max disconnection time and max Zs, max time is 5 secs as it’s supplying another dB, would/is this fuse equivalent to bs 88-2? Giving max Zs of 0.78, as I have read that bs 88-2 is the U.K. version of HD 60269-2 but not the iec version?
Could anybody point me in the right direction to confirm it is equivalent? Very confused right now.....

The fuse manufacturer should be able to confirm if it meets BS 88-2 (or BS HD 60269-2). The manufacturer probably includes this information on a datasheet that will be available somewhere.

Same as BS88-2.

As always many thanks chaps, the unit was a lewden one from tlc and I’ll be honest untill I came to fill out the cert I wasn’t aware it would cause me such a headache ha ha

In future always best checking the max zs for the mccb before when designing the circuit has some makes have quite low ones.
