What pitch is the cutters on the chain. From measurements I know it is 3/8th but is that low profile?

The pitch of the cutters on the MasterForce CSB401 chain is 3/8 inch. Yes, 3/8 inch is considered low profile when it refers to the 3/8" low profile (3/8LP) chain type, which is common for smaller saws.
