Blown capacitor. Actually an MOV.

[wave solder]

MOV's are bi-directional and are designed to be fitted directly across the mains supply.

The size of breaker in the supply would make no difference to the device failing.

What causes an MOV to fail is too high a supply voltage.

[klugardo]

so there were 2 of these mov

1 blew the other was left.

if you look at the picture i uploaded you will see the numbers on the mov

now on my item it says just 175L20

but others have 175LA20AP and another has 175L20CP

[klugardo]

hey wavesolder

well its a 240 unit and its wired as 240

this is the power / ratings from the manual

POWER / RATINGS
Amp Rating at 208V 31.3
Amp Rating at 240V 35.6
KW Rating at 208V 6.5
KW Rating at 240V 8.6

[klugardo]

so the only thing i could think it was the amp breaker.

1 wire from breaker to the device.

everything done perfect.

it blew the minute i plugged it back in.

if it had been plugged and left i dont believe there would have been a problem

[markfff]

An MOV is typically used for transient suppression, and is a bidirectional (non-polarized) device. You will usually find them on the line side of the power supply. With the amount of lightning strikes you get in Florida it's not surprising to find it blown. Between that and the breaker, it probably saved the rest of the your device.

[markfff]

The scenario I suspect is that a lightning strike or other large transient shorted the MOV and blew the breaker. After you replaced the breaker, the MOV presented a short across the AC line.

i just installed 50a wire and breaker 9pm yesterday 75 degree weather clear skies

used 3 hours then unplugged.

woke up in the morning to cook breakfast plugged it in and BOOM the minute the plug touched the outlet.

all grounds and wires connected perfectly both ends.

just boom

[klugardo]

anyway thanks to you guys i will buy 4 of these monday and install.

fingers crossed i hope this fixes it im heart broken.

if you guys didnt correct me and tell me this was a MOV

i would have never been able to fix this.

thanks so much forum fam

What equipment in the MOV fitted in?

[Diabolical Artificer]

A MOV, as others have said, is to suppress spikes in voltage, they are often used in digital multimeters. So, if your meter or power supply in your case sees too much voltage on the input, the extra voltage is shunted to ground through the MOV, it "absorbs" the extra power, think of it like a cartoon cat swallowing a stick of dynamite. Instead of getting blown to bits it just inflates with the only damage being a puff of smoke and a surprised look on the cats face.

In your case the MOV has seen too much dynamite, or voltage and has come to bits. Before fitting new ones and just plugging the power supply into the mains, you need to check for other faults further into the circuit or there's a chance you power supply might go BOOM. Hope that doesn't come across as too simplistic or patronising.

hello everyone

been trying to order this part and nobody seems to be able to tell me what the difference is between a

175LA20AP
or a
175LA20CP

[Herald1360]

Quite possibly nothing as far as electrical specs go. It could simply relate to mechanical aspects like lead length or materials used to plate the leads etc.

[wave solder]

With a little use of Google and the information is all in these datasheets.

The Littelfuse AP range here:-

https://datasheetz.com/data/Over%20V...atasheetz.html

and the CP range here:-

https://datasheetz.com/data/Over%20V...atasheetz.html

[Station X]

To quote from the datasheet linked to in post #6.

Some LA series model numbers are available with clamping voltage selections, designated by a model number suffix of either A or B. The “A” selection is the standard model; the “B” selection provides a lower clamping voltage.

That datasheet doesn't mention a 'C' variant, but others probably do.

The 'P' following the 'A' or 'B' denotes lead free.

I'd still like to know what equipment the MOV is fitted to. There's been a hint that you can cook your breakfast on or in it?

[ms660]

CP = C-lll series so far as I can make out.

-It's good that all 4 are being replaced, as being subjected to spikes on the mains over the years they age in the process- like a cat using up one of it's lives!

this is the power board ASM

[joebog1]

For $775 I would expect the whole stove !!!!! My god that is expensive !!!!.

Sorry, just my thoughts.
