The main battery disconnect/circuit breaker on our 170 Montauk will not reset. Need to replace unit and haven't been able to find an outlet for them. The Whaler dealer wants $79.20--that aint gonna happen! The breaker is an E-T-A 2-5700 1G1 K10 250vac 28vdc 30amp. Have found them on the web and also called E-T-A directly, but listed posibilities have been distributors and don't sell to the public, or only in large quantities. Can anyone help me locate one of these, the unit couldn't cost more than $15.00. I used your search feature Jim and didn't find anything under battery disconnect/circuit breaker. any help would be appreciated. Thanks

If you are looking to protect your wire harness, pull the breaker out of the circuit and replace it with an in-line 30 amp fuse. Fuses are available in all load ranges and configurations.

You can install a 30 amp in-line fuse and keep two for spares for $10 to $20 total. Check out the mega-fuse line.

I went to the E-T-A site and used their distributor seach:

I entered the part number as 2-5700 and got a long list of stocking distributors. Included in the list of stocking distributors was DIGI-KEY. They are glad to sell to anyone in any quantity.

Using the DIGI-KEY site search I found this listing:; keywords=2-5700

I did not see the 30-Ampere model listed, but you ought to call them and see if they have it available. Sometimes they don't list every possible component.

Here is their price for the 25-A model: dll?Detail?name=302-1292-ND

A search on E-T-A produced this article from the archives:

DigiKey only had the breaker up to 25amp. They've referred me to another vendor, Allied, so I'll try them. Why is such a simple part soo hard to come by?
