This is a 12 Volt 10 Amp rated SPCO (single pole changeover) miniature relay enclosed in an IP67 sugar cube package. These relays have many uses in renewable energy applications in which a low-power low-voltage solar powered device controls a high-power and/or high-voltage appliance.
IP67 means dustproof and waterproof for at least 1 hour at a depth of 1 metre.
The relay coil is rated at 12 Volts and has a coil consumption of 360mW. Therefore at 12 Volts a current of just 30mA is sufficient to trigger the relay. The relay contacts are rated at 10 Amps at 240 VAC (mains electricity) or 12-24 VDC and so can easily be used to switch on 12 VDC and mains-powered pumps, lighting and much more.
Technical Specifications
This relay has operate and release times of just 10ms and 5ms respectively, and a coil resistance of 400 Ohms.
It is just 21.5 15.5 x 17mm in size.

Idec RTE-B22-12V 12V AC/DC Electronic Timer Relay Delay on Break and Single Shot. Select Operation mode by DIP switch.
This Bosch 12V, bracket mount SPST relay is rated for 20 amps. It has a suppression resistor across the coil to prevent kickback to the coil-driving circuitry.
This eliminates the need for an external coil suppression device.
