What relay should I use with this for a 12v 3a application?

I used a Chicago Sensor relay P/N RLY004 with base SQC002 sourced from Aqua Hub. $8.00 for the relay & $5.00 for the base. I used this relay to power a Jebao WP-450 (PP377) water pump and actuate a solenoid valve to auto fill a water feature reservoir. This relay handles both operations simultaneously. I chose this type of relay to simplify replacement of relay if necessary. So far after two years of operation the relay has operated flawlessly.

Can it be switched from n.o. to n.c.?

you can rig it up so it sits upside down in the water I suppose.
