Electronic – Calculate RC snubber for 240v ac coil relay

You can use four diodes to the supply rails like for motors in an H-bridge.

See for example here.

USA standards require motor horsepower ratings for relays used for motor control. If you look carefully at the amzn.com/B00R7TTSMI relay you will see Hp ratings on the top of the relay. Some online info for the SSRs mention heating control - not good for a motor.

Addes re Coil Etc.

If you look up the Songle SLA-05VDC-SL-C that you can see printed on the relay, you will find that the coil requires 185ma. If you look carefully at the pictures on Amazon, you will see a diode that must be across the relay coil. For an AC motor, you would not use a diode across the motor, that would be a short circuit on the power supply.

Solid state relays that are rated for motor use have Hp marked or stated in the spec. sheet.

Note that the above relay is marked with UL's cRUus mark (backwards R). That indicates that the relay is a UL listed component that is also listed per Canadian requirements for the ratings published.

The Amazon material mentions "amp transfer for heating ...." The amp ratings and transfer duty are only for resistive load. The Hp ratings are only ones applicable to motor duty (non reversing).

Before asking questions here, you are generally expected to find and attempt to interpret the spec sheets. Then ask about the parts that you don't understand and give a link to the sheets that you have questions about.
