Eaton offers the XTRE10B31TD line of 10 AMP 4 pole control relays that come with three different contact configurations: 2 normally open/2 normally closed, 3 normally open/1 normally closed and 4 normally open. And with the addition of a 4 pole front mounted auxiliary contact, you can have any combination up to 8 poles in a narrow design that mounts directly on standard 35mm DIN rail. In addition to the auxiliary contacts, you can add an on-delay or off delay timer that snaps onto the front of the relay for easy installation.
