1.0 out of 5 stars I have bought three of these and all three have had a complete meltdown after a few months.
Reviewed in Canada on February 7, 2021
These might work fine as long as you are using them with less than half the rated amperage. Otherwise they all melt down. 40 amp relay running 25 amps and all three melted.

1.0 out of 5 stars 3months of use and now one of the relays melted
Reviewed in Canada on October 16, 2020
bought 4 of these units, after 3months of usage, one of the relays melted the connector.
Very lucky it didn`t cause a fire. I know it wasn`t a heat problem as i purchased these with the heat sink and have monitoring of temperature for the relays.

From reading others reviews, this seem to be a design problem with these relays.
