We've released the Seeed Relay Selection Guide, it will help you choose the relay that best suits your needs.
The SPDT Relay(30A) is a high quality Single Pole Double Throw Relay(SPDT).The Relay consist of a coil, 1 common terminal, 1 normally closed(NC) terminal and one normally open(NO) terminal. When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity. When the coil is energized, the common terminal and the normally open terminal have continuity. This relay's coil is rated up to 5V and the contact is rated up to 30A (@250VAC, 30VDC). Use it to control AC appliances or high current DC devices.
Please exercise great care and safety precautions when working with mains voltages. If in doubt, contact a professional such as a licensed electrician for help.
Grove interface compatible

A solar boiler is great because it gives you hot water using free-sun-energy, but what if there is not enough sun or someone already used all the hot water ? This project helps you take the right decision. It warns you when you run out of hot water and al
Wiki of Grove - SPDT Relay(30A)
I would like to know what the amperage rating at 110v 60 Hz AC is.
The current of 110VAC is the same to current of 250VAC, so the current is 30A.
What's the current rating and wire range of the screw terminal
Hi Sadri, current rating is (@250VAC, 30VDC 30A). and it is recommended that the gauge wire should be a brand-qualified one with assurance of 250VAC/30VDC 30A. Usually there are some intruction on the wire.
