Always double check whether you are sending to a BCH address or a BTC address. Never send Bitcoin Cash to a BTC address. Never send Bitcoin to a BCH address.
You are lucky you sent it to an address that you have the private key for. If this had happened with an exchange your coins would have been effectively lost.
According to Ledger's support page, you should be able to simply log into your BCH wallet and access your BCH there:

Unless you sent it to a SegWit address (starting with "3") in which case -- sorry for your loss.
I think OP is referring to Blockdozer, which is a Bitcoin Cash blockchain explorer.
