Megger 1552 fuses

[ezekiel]

managed to blow a fuse

data sheet says they are:
Replaceable 500 mA (F) HBC 10 kA 500 V

however inside was a:
siba F500 mA 600v and a spare (thankfully)

tried everywhere so fa and cant find a replacement - can any1 help?

If your fuse complies with the standards stated in this siba pdf then it looks like its an even better protection fuse than the standard replacement one that megger states.

What are the dimensions of the fuse?

 

[ezekiel]

32 mm x 6 mm

thought they would be easy to find out of mft but proving a little difficult

http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=2099276 is about the biggest HRC I can find from the normal places, it is 10kA @ 440v. Maybe worth phoning megger and asking them to send you some.

The breaking capacity @ 500v 1.5kA is significantly lower than meggers recommendations though of 10kA for compliance with their spec for a meter. maybe RS have alternatives? or it may need a call direct to Siba for a list of UK dealers for that specific rated fuse?
edit
just missed Sparks addendum and agree that a call to megger themselves is probably the best bet as they know what is needed to make their meter comply with the standard its been given.

thanks for effort, will ring them on monda

You can buy the fuses direct from Megger on-line, you will need to register.
They are rather expensive and the shipping charge is high so it pays to buy quite a few.

2 packs of five cost £21.66 + VAT + £7.00 delivery total £33.67

 

[ezekiel]

wow expensive, but needs must - thanks very much

Dont be fooled into paying Megger silly amounts of money for a simple fuse £33.67 is daylight robbery!!! Do your homework - RS do them at £6 each

just re-read the previous post - 2 packs of 5 for £33.67 (£3.36 each) is pritty good! As previously said - look around!

Its not so much putting a "simple fuse" in these days and especially in a calibrated meter what with everything having to comply with standards or warranties being affected.

What wold be the point in paying extra for a meter that is approved for the work intended only to compromise that approval by scrimping on a £3 fuse?

 

[ezekiel]

checked there site and a pack of 5 comes in at £20 about £4 a fuse so not as bad

I know this is a old post but i have just seen it.

The fuses from the link above are the correct ones. The 440v fuses are for the 20 & 25 amp range, below this are 500v.

The prise is £0.308 each or £3.08 for 10 and this is what i buy them at.

They are prity much standard in most testers these days.
