Jeanneau 42DS anchor tripping

[Rob_Webb]

It raises ok on short anchor lifts e.g. <15m. But anything in the 20-30m range it trips multiple times - the other day I had to reset the trip 5 times on a 30m lift. That's not right.

Is there an inherent flaw in these systems e.g. windlass underated and over-heating?

Sorry I can't recall windlass make but it's a standard 2006 model.

By tripping do you mean the circuit breaker trips or the thermal cutout in the windlass? If the former a slightly bigger beaker might be worth a try?

Yes, our breaker started tripping years ago and then failed fairly quickly. Internal examination showed that it was designed to minimise arcing but still showed signs of damage. I did a lot of digging and found that the standard trip would not stand a surge for very long. I did finally manage to source one which would fit, wasn't too expensive, had exactly the same rating but would take an initial surge for much longer. That has been fine for many year now. I'll dig out the details.

I haven't found the order & receipt or detailed notes yet but did find this information from time I was trying to get a replacement.

Carling Breaker specs.
C-series, panel mounted, single pole, DC long delay 100A breaker with M6 threaded studs & toggle switch.
I think that the carling code would be similar to CA1B-016810-6D2 (based on some C-Series documentation I managed to find).

Carling
C: Series
A: Handle, one per pole
1: Single pole
B: Series Trip (Current)
0: Without auxilliary/alarm switch
16: DC long delay (36 is also long delay both AC & DC)
810: 100A
6: Stud M6 threaded
D or U: Actuator legend black with white On/Off (U is short toggle)

I ordered a Carling CA1 B0 30 100A 2697 from Acorn Engineering around Sept. 2012 for approx. £25 + delivery.

It fitted fairly easily, though I think the retaining screws were in a slightly different location. I seem to remember widening the hole slightly and drilling one new hole (can't remember exactly). It looks vey similar to the original part which was much more expensive and not so easy to find.

The replacement had a much better delay curve, you can find that information here.

Wow, price has shot up since 2012 and is now £73 + delivery. Wish I'd bought a spare just in case as it is in almost daily use for 6 months every year.

Great thanks will look into this.
